So, in order to spare my fellow Space Marine fans the effort of rewatching every multiplayer video of Space Marine, I've decided to put together a list of all weapon, perk, and armor customization options for both Space Marines and Chaos Space Marines so that you can begin creating your future marine now and have it ready when September 9th hits. I'll try to keep it updated as new information comes in over the next six weeks!

(If you see an empty entry, it's because I couldn't find the official description in any videos yet. If you can find them post them below and I'll add them in! Also I left out the reskinned weapons such as Relic Bolter and Possessed Chainsword, as they are the same stat wise as their normal counterparts.)
