No, Trine isn't available on PSN ... yet! However, a brand new trailer on the PlayStation.blog makes us wish we could play it on our PS3s right now. (Note: You can buy it on Steam ... but it'll cost you some more.) This new footage focuses on the co-op gameplay and how multiple players can take advantage of the physics system to help each other traverse the game's 16 levels. Unfortunately, there's no release date revealed on the blog, other than a simple "coming soon." Boo. Soon doesn't mean today, does it?
