I tried it again and i didn't feel any better even with the knowledge about the barrels. I'm willing to say maybe i just suck but once the first enemy appears it's game over every time. Some times his buddies gets their shots in. Plus due to the heavy shooting if even attempt to get near a barrel i'm dead from the explosion. This is definitely chaotic, but I don't feel like the chance to win is very strong, and maybe it's just me.
