I'm actually surprised, it was good!
You gotta make another that's longer, has more weapons, and you can like move your barricade to other places durring the day. And what would be really cool is if it was online multiplayer where you choose your weapon and backup, place to barricade, and have other people go to your barricade and help you out, or you to them. I dunno man you da boss, but if I were you, I'd make a second. It'd definately get frontpage.
