I can't really tell what was the original idea for those vests but they are mainly custom vests modelled after existing ones.

They are indeed ballistic masks and not hockey masks. :P

Finally, this game is all about coop. It was built on coop and grew with coop in mind. It's an Army of TWO and you will always be two. If you don't wish to play coop, an AI will accompany you.

Lots of fun, lots of locations, very current and it's quite a deep story if you pay attention to it. A shitload of guns and a nice coop feel. Gears inspired us to drive it this way when it got released and as you will see it looks far much better than Gears. Visuals are just out of your mind and these two badasses will wreck havoc! I love to mow down enemies with a custom M249 or snipe guys from afar with a custom SVD.
