Posted over at the Champions Online official site:

Get into the game with Cryptic Studios at Gencon and Penny Arcade Expo this year, with a playable demo of Champions Online!

We'll have stations set up at our booth so you can be one of the first people to experience the fast-paced, high-adrenaline combat of Champions Online. But that's just the start of our summer convention fun - we'll also have demos of the Champions RPG (including some run by Hero Games' own Steve Long), sponsored RPG events, trivia contests and more!

You're not going to want to miss your first chance to play Champions Online ... or the great prizes we'll have available. If you ever wanted a ping-pong ball gun just like Foxbat's, you better be at Gencon or PAX!

Talk about this in the forums!
