I'm on it!

Bought it last night, excellent excellent game. Bargain!

I thought the actual game was offline only.

Definitely only local co-op in this game.

The PDA games are indeed 4 players online though.

this game was frustratingly hard, on the website and on console.

Really, I thought it was awesome. It is hard, but if you play on co-op and don't mind having to reply levels (like old school arcades), I think a lot of people will find they like it.
