Arma 2 - Greatest game in the universe 

It's ARMAZING!
Practically everything here can be accomplished in vanilla Arma. The only mods I made use of (which seldom appear in the video) are effects and sound based, 'cept the chicken - that's done by SLX wounds. Oh yeah, and the zombie. He's from Undead mod.
The crazy vehicles are built in the editor using the AttachTo command.
