i thought of it myself.
when i finished crysis singleplayer i decided to play the game all over again in easy mode with no guns. this involved grabbing enemies and throwing them around, picking up objects and throwing them at enemies, throwing enemies on enemies, speed running and jumping into enemies to knock them down and stuff like that. it was while doing that i found out that i could pick an enemy weapon in midair if i powerjumped with him and knocked him out. youll be surprised at the results. you can throw enemies over hills, on houses, on watchtowers with snipers XD, throw enemies reealll far away.... its awesome fun. hold an enemy, power jump and power melee him in the air upwards to see how high he can really fly.
