Geat game!
you should put a pause button and I agree with the guy under me
saying "it'd also be more fun to be able to walk around, explore
the city with your team" but while your searching you should
have a person looking out to see if zombies are coming.
Also you should be able to get more guns and upgrade
your teammates and their guns.
P.S. For any one that says zombies can't run, I think they might be able to. People should stop saying, "Zombies can't run in real life" How do they know? have zombies existed in real life? No. So they don't know If zombies can run or not.
