Crysis Warhead®

Crash with Anti Aliasing. And it's a sprinting simulator.

Sure, it's more of Crysis one but the mission design is more varied and back then it came with some really cool multiplayer maps that I enjoyed, made by Sven ‘c4te’ Metzge (RIP). It also felt way more polished at release than the main game while its story is not much worth to highlight and the play time on this one is a bit short when looking only at the singleplayer.

If you liked Crysis, you'll love Warhead too. It's a standalone DLC. It's short, but it shows everything it needs to. The only problem is that the game crashed constantly in the last three missions. I partially solved this by disabling VSync, but it also crashed sometimes during cutscenes.
