Frozenbyte has come out with a new Trine Enchanted Edition today on PC that's a remake of the original game in the Trine 2 engine, complete with online and local co-op play and mid-level saving functionality. It's currently on sale for $2.99, which is 80 percent off. Better yet, this is a free upgrade for folks who already own Trine on Steam, GOG.com, or the Humble Store.
If for whatever reason you want to play Trine without these upgrades, that's still possible too. Mac and Linux versions of Enchanted Edition will be here shortly, and the studio says it will have Wii U and PS4 ports out later this year as well. Huge props to Frozenbyte for this one.
