None of them have multiplayer. Edit: Oh wait, multiplayer as in Escalation? So... what, you can't play Escalation on the PC version?
But the Steam page lists Multiplayer Escalation right there. Unless they think the fact that this game is 10 bucks cheaper on PC means that putting less content on there is acceptable. These are the guys who made Loadout, a PC multiplayer-only game.
You know what I think? I think Steam probably ripped the description from the console versions before they even greenlit the game for Steam, and so they just kinda tossed it in the page when they said "Fuck it, put the game on Steam, make it cheaper than Fall of Cybertron too."
Maybe (in drafting the sentence) they were intending to leave out the WiiU and 3DS versions and leaving out PC was accidental?
Sorry, that was terrible phrasing on my part. I meant whoever put up the description, not Steam in general.
