A new BattleTech mod out this week condenses the mech strategy game's lengthy campaign down to a bite-size maximum of eight hours by giving you a 120-day time limit to build up your fleet and reach the campaign finale. If you die in the process, that's it: game over.

It's inspired by FTL, which means the star map that you play on will be randomised each time, and will be a lot smaller than the base game's map. The idea of fighting through seven hours only to fail at the last sounds daunting, so it's not for the faint-hearted, especially as every faction in the game will dislike you from the start.
