@alex4500:
1) 50K goes fast to get.
2) I'll make a red dot
3) I'm always working on the lag
4) I'll fix the AI, so you can command it to specific spots
5) There is no problem to kills the big zombies if you use a good gun.
6) Since this game normally goes to level 15, you'll stack up enough points, the upgrades are really good...
