Awesome
okay, every1 who thinks they know what to do, stfu. The people with you are completely useless unless you have 6, and then its only the 1 with the rifle. Basically a waste of time to get them, end of story. Spend all ur damn time looking for weapons. That way you're ahead of the curve for zombie blasting. You'll be pleasantly surprised if you continue looking for weapons after you get the final silhouette on the wall filled (it takes awhile). 'Till you get all the weapons, I agree with SonicEx3 below me. Rapidfire/shotgun works best. Some weapons are useless, namely the sawnoff and the gun before the ak (dont get me started on ur beginner pistol). I prefer rapidfire/chainsaw myself, but hey, all depends on how you play. Once you get the full wall, you can stock up on all the damn teammates you want.
Onto the review. Awesome game, I've played 5 times and still not bored. For best results, blast metal to heavy metal for 30-40 minutes while ripping zombies apart with your vicious arsenal. Satisfaction guaranteed.
