The announcement was contained within "Atlus' E3 2010 Lineup", which also offered word of a new title from Zeno Clash maker ACE Team dubbed "Rock of Ages." No word yet on the specific platforms for either game, though Zeno Clash hit PC and Xbox 360 while Trine is available on PC and PlayStation 3.
If you've yet to sample the charm of Trine, we've got a demo over on FileShack.
In addition to Trine 2 and Rock of Ages, Atlus will also be showing RPGs Etrian Odyssey III (DS) and Knights in the Nightmare (PSP) during next week's chaotic festivities.
Maybe rephrase the headline?
"Trine 2 and Zeno Clash Maker's New Game Unveiled" made me think that those two dev houses have teamed up for a new game.
