How do I play game

Are you applying for ZAM membership? If so, I recommend you read this topic: https://undeaduprising.net/forums/topic/5593-requirements-template/#comment-36658. If not, then I'd recommend creating topics in the correct forum on the website next time. I understand that you are new, but you'll eventually learn.  

You're asking us how to play a game. I for one don't know what game are you talking/referring about. Maybe if you told us the game you were talking about, then someone would be willing to help you out. But I guess not.

isn't he clearly talking about zam?  and if he does he should go to unranked matches and go on  /UU/zombie annihilation mod and just join it. it will download and u can play it..... that's how I did it ......
