It’s no secret that Valve is working on several projects at a time, but it’s a pretty big secret what those projects are. Besides Half Life 3, or Half Life 2 Episode 3, we dunno much of what’s going on, besides the occasional hats for Team Fortress 2.
But according to new evidence, the studio is working on a science fiction game with the codename “SOB”. From the recently leaked DOTA 2 code, there are several references to “ep3″, “cstrike2″, and “SOB”. According to one rumor, the SOB includes code references to “nebula”, “npc_ship”, “ship_guns”, “client_ship”, “flightplan”, “server_ship” and more. We’ve also gotten some concept art from one of Valve’s artists, who featured it on his website — the concept art of a space ship which you can see above.
