So I just tried out the Beta zombie mode server and I feel like Human are too over powered just with the "Hold down trigger and aim". And since I tried out Nexon's licensed Counter-Strike Online, the zombie mode in game are well balanced, and have great atmosphere. Since the zombie mode in CSO are inspired by the original mode from your guys, I don't see why shouldn't I suggest it: 1) Human have limited ammo and required to reload, that make them careful with shooting. 2) Editted map and make them darker 3) Supple box drop every 30 second in random location, box resupply or special weapon 4) Zombie have faster speed and higher jump height. 5) Zombie dies, they stay dead. No respawn 6) Last but not least, unique zombie class and Special weapon. My English are not good so bear with me, here's how Zombie mode in CSO look like. And just my two cent to try to make it fun.
