While Trine has been out on the PC for a week or so now (we'll actually have a review later today), PlayStation owners have been clamoring for their title ASAP! The good news is a representative from the game's publisher has posted a brand new article on the official PlayStation Blog, complete with a co-op focused trailer.
The bad news is, no release date was given.
The trailer gives a really good impression of the unique nature of the game's local only three player co-op mode. Thankfully we have it on good word from the game's developer, Frozenbyte, that they are planning an online cooperative patch for all platforms - though once again, no date was given.
