Crysis, most common glitches I’ve encountered:
-Weapons that soldiers drop after dying get stuck in the wall and shake like crazy
-Sometimes at the start of a chapter (most commonly at the start of Recovery) Nomad holds the last weapon selected with only one hand until you fire, reload or switch weapons
-Sometimes you can die instantly if you try to walk on top of or run through large objects like shelves, lockers or metal containers,(most common in the chapter after the scientist guy gets frozen)
…and the two most famous:
-Soldier standing in the toilet in the first mission
-Soldiers driving around in vehicles with no back wheels
