No, wait. I'm a little upset only because I am looking at it this way, and please correct me if i am wrong.
I know this is standard fare for the most part, I get that. But what throws me off is the fact that the Survival mode that comes with the game is a demo'ish sorta thing. Like a tease. (Basically Isolation doesn't have multiplayer, which is fine, but this is equivalent for the sake of argument here). That would be like COD or The Last of US coming out for $60 only giving you the single player and including a single multiplayer map tease level enticing you to buy the "full multiplayer experience" for an extra $30. I wouldn't really have a big problem with what Creative Assembly is doing here if it came with 4 areas to play this survival mode in, instead of half of one. Then release the expansion packs later and so on.
