I'm thinking of adding a few game modes for single player heres what I got so far.
Campaign - Normal Single player right now but with a story line and objectives
Gored - Kill, Kill, Kill! Thats your main objective the more kills you get the more zombies come after you
House of Horrors - Your trap'd in a house with 1 member of the Hazmat team, do you have what it takes to keep the barricades up and the zombies out?
Survival - Like Campaign and Gored combined without a story line, or any real objective.
Let me know if you like them, and if you don't please tell me why and give me a better idea, thanks.
Progress so far
Single player (Survival type mode) - 73%
Multi-Player(Kill zombies with other players) - 20%
Register System - 60% (Hopeing to link it to a site soon and make it to where you can only register it with your account once, so far its just a Registration Key)
Menus & Dialog - 70%
Story - 30%
