Instead of the idea posted in the last announcement, lets go for a SMOD: Outbreak style sitchuation instead as it doesn't require specialised maps. SMOD Outbreak is a HL2 Mod that changes the HL2 story to be that of a post zombie apocalyspe. After regaining territory, overwatch started making cities to protect it's citizens from the infected populace. Most of the overwatch cities are a police state of their own and citizens live in a life of oppression and fear. Pretty much a "At least we didn't get wiped out by zombies and we rebuilt ourselves into a very overprotective world"
