Episode 9 - Subversion

Behind every great video game comes a plethora of ideas, missteps, dead ends and almost-made-its. Usually these embryonic prototypes get dumped in an archive and left to digitally rot, cursed to never see the light of day or feel the loving caress of a player's mouse. Until today....

Watch Mark and Chris dissect what it means to fail when trying to make a game, navigate the creative maze, meet with triumph and disaster and treat those two imposters just the same and remember; there is always light at the end of the tunnel.

If watching Mark and Chris isn't enough to get your rocks off then you can even play these — buggy, broken, well-conceived, but ultimately doomed pre-alpha builds below. We're asking for 5 bucks, but you can pay more if you want, in the virtuous knowledge that every penny we make will go to highly deserving charity, War Child.

Your mission, should you choose to accept it, is to relieve the Imperial Bank of 151,000,000 USD worth of bullion from the safe in the branch on Main Street. The bank's security systems have been judged inadequate by HQ and should not pose a problem for a team of your calibre. Tools and transport have been deposited at the usual rendezvous. In the event of failure you will be disavowed…

In 2007 Introversion attempted to set a heist game in a procedurally generated city. Despite our best efforts over many years our skills were no match for our ambition and we admitted defeat. We called this project Subversion and for the first time you can play with the tech and try your hand at the missions that we did create.

Episode 8 - Praxis12 July 2021
YouTube Video Thumbnail

A trillion molten shards explode from the impact zone, scintillating in the light of the amber gas giant as they cool. With the enemy battlecruiser neutralised, your attention turns to the evacuation of the scientists from the failing outpost before warping home. You won, but the mission hadn't gone as planned, the new gatling gun placement had obscured the docking sites and the laser array couldn't orientate to get a targeting solution. Time for a complete re-build, before accepting the next job.....

Build a ship, accept a mission, level up and improve your craft design in Praxis the arcade space-builder prototype.....

Episode 7 - Wrong Wire11 June 2021
YouTube Video Thumbnail

Yo, back up now and give a brother room - the fuse is lit and it’s about to go.....

Welcome to Paradise City where the Midnight Toker is wrecking chaos with a series of highly charged devices configured to give Detective John McPhane a really bad day. Play on your desktop or strap on your VR headset, just don’t cut the wrong wire!


In this month’s fail master-class, Chris and Mark take a look at Wrong Wire - a puzzle based exploder. There are only three levels, so if you want to have a crack at them yourself make sure to download the build using the link that SendOwl sent you when you purchased access to this series, and give it a try before you watch this month’s vid.

Episode 6 - Deep Space Industrial5 May 2021
YouTube Video Thumbnail

The meteor orbits the gas giant, perilously close to the jump-portal. A lone astronaut bursts into existence, mining drill in hand and sets about extracting the valuable ore. Another appears and follows suit, then another….

Deep Space Industrial was an attempt to scratch a space-builder itch, learning from Spacebots and Order of Magnitude. Third time’s a charm? We’ll let you be the judge of that…..

Episode 5 - Voxel Factory1 April 2021
YouTube Video Thumbnail
Chris' 3D version of Factorio, set in a Darwinia-esque landscape you can mine ore, lay conveyor belts, create fabricators and craft objects - just watch out for those nasty ant swarms. Full nod to Wube for the inspiration behind this prototype, but cloning great work isn't really our style - hence the decision to add this one to our every growing list of might-have-beens....

Episode 4 - Nanotech4 March 2021
YouTube Video Thumbnail
Less of a game and more of a toy, Nanotech is set in the microscopic world of a petri dish, exploring the idea of dragging molecules, virii and amino acids together to create tiny creatures that operate on a sub-celluar level to stich injuries in 22nd century super-soldiers.

This month we take a look at Megaprocessor, a 3D electronics sim that lets you turn a NOR gate into 1 bit memory, wire those bits together to form bytes and plumb all that into a clock pulse to generate a 255 counter. Super-sexy, bang, bang, jump-out-your-skin it is not, but if you ever get a hunger to break out your old electronics kit…

How it works

Roughly once a month, Mark and Chris will release a video on the Introversion YouTube channel discussing an Introversion Prototype — what worked, what didn’t and why we ultimately abandoned it.

When we release the video we will add the playable prototype to the failure bundle. By making a donation to War Child using the links on this page you can access the bundle and will automatically be granted access to the new prototypes as they are released.

There is a minimum donation of $5, but please give more if you are in a position to do so - all of of the proceeds will go to helping children directly affected by war. Any questions get in touch - support@introversion.co.uk.

War Child

Wherever children are caught up in wars — whether they’ve lost their homes, families, schools, or been forced to take part in atrocities — War Child make it their mission to do what they can to help them. The work has evolved from temporary food aid to ongoing, sustainable projects that improve the long-term outcomes for the most vulnerable and marginalised children in conflict areas and they are still the only charity dedicated to protecting and speaking up for children affected by war. With more than 25 years of experience, War Child are acknowledged as experts at what they do, and a leading voice in the sector.
