If you have just joined and are looking for things to do, there is a guranteed something. See below for some of the things you can do.
I have a need for fellow players to come on and give information. I often play through guest accounts and level slowly. I do not have access to all weapons as a result, and I do not have deluxe. Contributions for both are welcome. Also, proofreading and fact-checking is very much appreciated.
Even if you don't play shellshock, it would be helpful to have fixes to items that might not make complete sense, add stubs to stub pages, and fix any grammar errors or bad links.
Who knows? Perhaps this wiki will inspire you to play the game.
