i like the realism they have to it, like the weight of guns an ammo and the fact that you can infect people
Ikr?
Also, I love it when people on aquatic beta always count on someone to go and get the item. Then everyone heads to the exit, and they kept saying: "OH stuff DID ANYONE GET THE ITEM??"
Yeah, then were forgeted.
This game got deserted once Left 4 dead arrived, but it's a fun game seeing as you don't need to reach an objective point, just survive.
On ZPS there are like tons of Objective maps, and some you just survive.
