Trigger Happy’s Sam Prebble on perfecting the survival horror of Total Chaos - and playing the genre’s classics for the first time

“A lot of the quality of life things I put in were taking away from that whole tension of fighting monsters,” says Turbo Overkill dev

“Coming off Turbo Overkill has been great,” Trigger Happy’s Sam Prebble tells me over call. “That game’s development… I mean, it worked out. But it was very messy because it was my first game and I didn’t know what the hell I was doing. So I found myself, when it came to pumping content out, I was like: oh, shit. This code base is fucking awful. Like, I can’t put stuff together easily. I’m running into bugs everywhere. But now shit just works!”

You might know Sam Prebble as Trigger Happy Interactive, the solo developer behind frenetic FPS Turbo Overkill. Before that he went by a different name, attached to a very different project. Total Chaos , first released in 2018 under the moniker Wadaholic, is a total conversion mod for Doom 2. With its focus on a thick survival horror atmosphere of tension and disempowerment, it’s about as far removed from Turbo Overkill’s manic, Doom Eternal -inspired action as a game can get. As Prebble puts it, the only thing the two projects have in common is the first person perspective. Even so, he found himself returning to Total Chaos after wrapping development on Turbo Overkill, resulting in the standalone remake.

As the name Wadaholic suggests, the original Total Chaos wasn’t Prebble’s first Doom mod, but it ended up being the one that resonated most with an audience. “It stuck around for a while,” he says. “Like, I didn’t just release it and it kind of died on the spot, like some stuff that I had released in the past. I felt like: I could do a better job of this if I were to move to a more conventional game engine.”

Prebble’s interest in survival horror began through osmosis. “It’s kind of funny,” he says, “because I did get a lot of inspiration from, obviously, the Silent Hill games while I was developing the mod, and those influences have definitely stuck with the remake. But the funny thing is, I’ve never actually played Silent Hill. At the time of developing the mod, I never played Resident Evil either.”

Still, he loved the atmosphere of games with “lower graphical fidelity” like the Let’s Plays of Cry Of Fear he’d watch endlessly. He originally started the reimagined Total Chaos in Unreal, but moved on to Unity after finding the fidelity too high. “And the expectation following that, you know, trying to create a full 10 to 12 hour game with that fidelity was going to be far too much of a task for just one person.”

To help bring a taste of the mod’s lo-fi atmosphere into the new project, Prebble says he’s working on implementing an optional retro mode. “Super low-res, chunky textures and chunky, chunky models.”

Otherwise, he says the biggest challenge of adapting the mod has been getting the balance right - wanting to update things for a new audience without straying too far from the original’s spirit. “I don’t want to try and go too far in one direction and change what people loved about the mod,” he explains. During Turbo Overkill’s early access period, a lot of the features he’d included were just intended to be temporary additions. But as he went to make changes, he’d find players had grown attached to those placeholders. At the same time, he’s trying to keep a new audience in mind, “so you kind of have to try to take away some of the jank and make it play a bit nicer.”

“The best example I can think of is something as basic as player movement,” Prebble says. “The mod was very slow. There’s deceleration on the player speed, so if you stop running you don’t stop instantly. I took that out in the remake, because that was basically an engine limitation. But then I found in testing that the game was too easy. A lot of the quality of life things I put in were taking away from that whole tension of fighting monsters.”

He says now his approach is “basically just going off feel”. He’s planning on putting out a demo for Total Chaos early this year, but it won’t have an early access period like Turbo Overkill. Instead, he’s learned to rely on testing more. “It’s very easy to just get caught and stuck in that developer cycle of: you’re looking at a game every day, and you don’t know how it’s going to look for someone who’s jumping in fresh, right?”

Something that’s staying largely the same in this new version is the setting: an abandoned mining colony and the surrounding isle influenced by Japan’s Battleship Island . “The story in the mod was basically put together in the last, I think, month of development,” Prebble says. There’ll be new discoveries to make this time around, but the story is largely the same. “It’s mostly still, you’re fighting through this island, and you’re piecing together a story as you go.”

“Originally I was going to have the whole island connected,” he says. “I wanted to have the whole thing be seamless. But the more I worked on it, the more I realised that was kind of a pointless endeavor. In the mod, you never went back to areas you previously discovered. I felt tying the whole thing together would feel slow - you’d basically feel like you’re not making much progress.”

Instead, he’s focused on tweaking the familiar. “You’ll enter a level - if you played the mod before - and be like: ‘Okay, I remember this space.’ But the more you play through the level, the more you start to realize: ‘Okay, this is different.’ And then eventually you’re just thrown into this in completely new area that you don’t know.”

As much as I like the idea of setting out to create a survival horror game without having too much experience in the genre, not least because of how this might insulate you from some of the more familiar tropes, Prebble’s now spent some of intervening time getting acquainted with the touchstones he’d missed, like the Silent Hill 2 remake and Resident Evil. As for what he feels makes a great survival horror game, it’s all down to atmosphere.

“The thing I love about it is you don’t have to have a high fidelity game that has, you know, all of this crazy rendering tech to make something atmospheric. You can make something just bare bones. The videos I see online of indie horror games, some of them might not look like much, but they just have this completely unsettling atmosphere.”

“That, and trying to make the player feel helpless. You see that design everywhere. You have a very limited arsenal. You have a very limited movement set. I feel like those two things alone are kind of the most important things to me.”

The Steam demo for Total Chaos is coming “very shortly.”

Looking for more Arc Raiders Blueprints? It’s a special day when you find a Blueprint, as they’re among the most valuable items in Arc Raiders. If you find a Blueprint that you haven’t already found, then you must make sure you hold onto it at all costs, because Blueprints are the key to one of the most important and powerful systems of meta-progression in the game.

This guide aims to be the very best guide on Blueprints you can find, starting with a primer on what exactly they are and how they work in Arc Raiders, before delving into exactly where to get Blueprints and the very best farming spots for you to take in your search.

We’ll also go over how to get Blueprints from other unlikely activities, such as destroying Surveyors and completing specific quests. And you’ll also find the full list of all 75 Blueprints in Arc Raiders on this page (including the newest Blueprints added with the Cold Snap update , such as the Deadline Blueprint and Firework Box Blueprint), giving you all the information you need to expand your own crafting repertoire.

In this guide:

• Full Blueprint list: All crafting recipes
• Where to find Blueprints in Arc Raiders Blueprints obtained from quests Blueprints obtained from Trials Best Blueprint farming locations

What are Blueprints in Arc Raiders?

Blueprints in Arc Raiders are special items which, if you manage to extract with them, you can expend to permanently unlock a new crafting recipe in your Workshop. If you manage to extract from a raid with an Anvil Blueprint, for example, you can unlock the ability to craft your very own Anvil Pistol, as many times as you like (as long as you have the crafting materials).

To use a Blueprint, simply open your Inventory while in the lobby, then right-click on the Blueprint and click “Learn And Consume” . This will permanently unlock the recipe for that item in your Workshop. As of the Stella Montis update, there are allegedly 75 different Blueprints to unlock - although only 68 are confirmed to be in the game so far. You can see all the Blueprints you’ve found and unlocked by going to the Workshop menu, and hitting “R” to bring up the Blueprint screen.

It’s possible to find duplicates of past Blueprints you’ve already unlocked. If you find these, then you can either sell them, or - if you like to play with friends - you can take it into a match and gift it to your friend so they can unlock that recipe for themselves. Another option is to keep hold of them until the time comes to donate them to the Expedition.

Full Blueprint list: All crafting recipes

Below is the full list of all the Blueprints that are currently available to find in Arc Raiders, and the crafting recipe required for each item:

Note: The missing Blueprints in this list likely have not actually been added to the game at the time of writing, because none of the playerbase has managed to find any of them. As they are added to the game, I will update this page with the most relevant information so you know exactly how to get all 75 Arc Raiders Blueprints.

Where to find Blueprints in Arc Raiders

Below is a list of all containers, modifiers, and events which maximise your chances of finding Blueprints:

• Certain quests reward you with specific Blueprints .
• Completing Trials has a high chance of offering Blueprints as rewards.
• Surveyors have a decent chance of dropping Blueprints on death.
• High loot value areas tend to have a greater chance of spawning Blueprints.
• Night Raids and Storms may increase rare Blueprint spawn chances in containers.
• Containers with higher numbers of items may have a higher tendency to spawn Blueprints. As a result, Blue Gate (which has many “large” containers containing multiple items) may give you a higher chance of spawning Blueprints.
• Raider containers (Raider Caches, Weapon Boxes, Medical Bags, Grenade Tubes) have increased Blueprint drop rates. As a result, the Uncovered Caches event gives you a high chance of finding Blueprints.
• Security Lockers have a higher than average chance of containing Blueprints.
• Certain Blueprints only seem to spawn under specific circumstances: Tempest Blueprint only spawns during Night Raid events. Vulcano Blueprint only spawns during Hidden Bunker events. Jupiter and Equaliser Blueprints only spawn during Harvester events.

Blueprints have a very low chance of spawning in any container in Arc Raiders, around 1-2% on average. However, there is a higher chance of finding Blueprints in particular container types. Specifically, you can find more Blueprints in Raider containers and security lockers.

Beyond this, if you’re looking for Blueprints you should focus on regions of the map which are marked as having particularly high-value loot. Areas such as the Control Tower in Dam Battlegrounds, the Arrival and Departure Buildings in Spaceport, and Pilgrim’s Peak in Blue Gate all have a better-than-average chance of spawning Blueprints somewhere amongst all their containers. Night Raids and Electromagnetic Storm events also increase the drop chances of certain Blueprints .

In addition to these containers, you can often loot Blueprints from destroyed Surveyors - the largest of the rolling ball ARC. Surveyors are more commonly found on the later maps - Spaceport and Blue Gate - and if one spawns in your match, you’ll likely see it by the blue laser beam that it casts into the sky while “surveying”.

Surveyors are quite well-armoured and will very speedily run away from you once it notices you, but if you can take one down then make sure you loot all its parts for a chance of obtaining certain unusual Blueprints.

Blueprints obtained from quests

One way in which you can get Blueprints is by completing certain quests for the vendors in Speranza. Some quests will reward you with a specific item Blueprint upon completion, so as long as you work through all the quests in Arc Raiders, you are guaranteed those Blueprints.

Here is the full list of all Blueprints you can get from quest rewards:

• Trigger Nade Blueprint: Rewarded after completing “Sparks Fly”.
• Lure Grenade Blueprint: Rewarded after completing “Greasing Her Palms”.
• Burletta Blueprint: Rewarded after completing “Industrial Espionage”.
• Hullcracker Blueprint (and Launcher Ammo Blueprint): Rewarded after completing “The Major’s Footlocker”.

Alas, that’s only 4 Blueprints out of a total of 75 to unlock, so for the vast majority you will need to find them yourself during a raid. If you’re intent on farming Blueprints, then it’s best to equip yourself with cheap gear in case you lose it, but don’t use a free loadout because then you won’t get a safe pocket to stash any new Blueprint you find. No pain in Arc Raiders is sharper than failing to extract with a new Blueprint you’ve been after for a dozen hours already.

Blueprints obtained from Trials

One of the very best ways to get Blueprints is as rewards for completing Trials in Arc Raiders. Trials are unlocked from Level 15 onwards, and allow you to earn rewards by focusing on certain tasks over the course of several raids. For example, one Trial might task you with dealing damage to Hornets, while another might challenge you to loot Supply Drops.

Trials refresh on a weekly basis, with a new week bringing five new Trials. Each Trial can offer up to three rewards after passing certain score milestones, and it’s possible to receive very high level loot from these reward crates - including Blueprints. So if you want to unlock as many Blueprints as possible, you should make a point of completing as many Trials as possible each week.

Best Blueprint farming locations

The very best way to get Blueprints is to frequent specific areas of the maps which combine high-tier loot pools with the right types of containers to search. Here are my recommendations for where to find Blueprints on every map, so you can always keep the search going for new crafting recipes to unlock.

Dam Battlegrounds

The best places to farm Blueprints on Dam Battlegrounds are the Control Tower, Power Generation Complex, Ruby Residence, and Pale Apartments . The first two regions, despite only being marked on the map as mid-tier loot, contain a phenomenal number of containers to loot. The Control Tower can also contain a couple of high-tier Security Lockers - though of course, you’ll need to have unlocked the Security Breach skill at the end of the Survival tree.

There’s also a lot of reporting amongst the playerbase that the Residential areas in the top-left of the map - Pale Apartments and Ruby Residence - give you a comparatively strong chance of finding Blueprints. Considering their size, there’s a high density of containers to loot in both locations, and they also have the benefit of being fairly out of the way. So you’re more likely to have all the containers to yourself.

Buried City

The best Blueprint farming locations on Buried City are the Santa Maria Houses, Grandioso Apartments, Town Hall, and the various buildings of the New District . Grandioso Apartments has a lower number of containers than the rest, but a high chance of spawning weapon cases - which have good Blueprint drop rates. The others are high-tier loot areas, with plenty of lootable containers - including Security Lockers.

Spaceport

The best places to find Blueprints on Spaceport are the Arrival and Departure Buildings, as well as Control Tower A6 and the Launch Towers . All these areas are labelled as high-value loot regions, and many of them are also very handily connected to one another by the Spaceport wall, which you can use to quickly run from one area to the next. At the tops of most of these buildings you’ll find at least one Security Locker, so this is an excellent farming route for players looking to find Blueprints.

The downside to looting Blueprints on Spaceport is that all these areas are hotly contested, particularly in Duos and Squads. You’ll need to be very focused and fast in order to complete the full farming route.

Blue Gate

Blue Gate tends to have a good chance of dropping Blueprints, potentially because it generally has a high number of containers which can hold lots of items; so there’s a higher chance of a Blueprint spawning in each container. In my experience, the best Blueprint farming spots on Blue Gate are Pilgrim’s Peak, Raider’s Refuge, the Ancient Fort, and the Underground Complex beneath the Warehouse .

All of these areas contain a wealth of containers to loot. Raider’s Refuge has less to loot, but the majority of the containers in and around the Refuge are raider containers, which have a high chance of containing Blueprints - particularly during major events.

Stella Montis

On the whole, Stella Montis seems to have a very low drop rate for Blueprints (though a high chance of dropping other high-tier loot). If you do want to try farming Blueprints on this map, the best places to find Blueprints in Stella Montis are Medical Research, Assembly Workshop, and the Business Center . These areas have the highest density of containers to loot on the map.

In addition to this, the Western Tunnel has a few different Security Lockers to loot, so while there’s very little to loot elsewhere in this area of the map, it’s worth hitting those Security Lockers if you spawn there at the start of a match.

That wraps up this primer on how to get all the Blueprints in Arc Raiders as quickly as possible. With the Expedition system constantly resetting a large number of players’ Blueprints, it’s more important than ever to have the most up-to-date information on where to find all these Blueprints.
