Yeah I can't really tell what's going on either
Well it looks like you won't be able to play online multiplayer for Cobalt until the game is fully released and until then they are focusing on a single player campaign with same computer multiplayer only. Right from the Alpha you will have a singleplayer/co-op campaign and a level editor to play around with. The campaign looks surprisingly fun, initially I thought it was just deathmatch modes and typical stuff like that but instead I learned that the campaign actually involves quite a bit of exploring and surviving in a hostile and futiristic environment. You can even crack safes and hack computers, but the game is mainly about running around killing enemies. Check out this video from Minecon, it shows off a bit of the singleplayer, and if you want to pre-order the game or check out more head on over to their main website. Thanks for reading and here's to hoping they have a demo sometime soon.
