There's separate single player and co-op campaigns. Basically two games in 1.
I've tried both and I like both quite a lot. Haven't finished either, going to hit sack.

Oh and potatoes play a big part in the game, its not just the promotion

Someone mind talking about the DLC? I'm hearing there is a shit load of it?

So far, the only things you can buy are skins/accessories/emotes (I'd read somewhere that at least some of the emotes unlock?) for Coop.

And they're not exactly cheap.

You unlock 8 common emotes in co-op. The ones you buy are unique to each robot (atlas, p-body). You can buy a bundle of the entire set of hats, flags, accessories, emotes, skins for like $35 or so (if you bought each one individually its like $80 worth of stuff)
Think hats for TF2 and thats what valve is doing for portal 2.
