From 1–7PM, Hecker will host the hands-on session in the Game Center's Open Library at 721 Broadway, followed by a talk about the game wherein he'll ask for player feedback and discuss development. He'll also be interviewed by Game Center director (and Drop7 creative lead) Frank Lantz. Hecker says this will be "the last playtest for awhile," so we'd suggest jumping on the chance while you can.
And if all that wasn't enough to entice you, yes, refreshments will be served. Head past the break for all the specifics (and the gorgeous full-size art for the event).
