Purge was created in such a way that individuals can create an incredible variety of characters with diverse skills, who need to cooperate in large teams to effectively purge the opposition from a map. Unfortunately, the game doesn’t support single player gaming with AI characters, instead relying entirely on the online community. That community hasn’t shown up yet, so Purge owners could regularly log on and find no one to play with. Even with only a few people on a server, the fact that each character is extremely specialized, and certain skills are necessary to any team (no matter how small) means that it is very difficult to have a good session of Purge at all. Hopefully, more folks will join in so that we can all discover whether Purge will achieve its potential, but until more they do, it’s not worth taking the plunge yourself, as there is no single-player game to tide you over.
