Helsinki-based indie developer RedLynx announced Big Thrills, a new expansion pack for its widely praised physics-based motorcycle racing/trick game Trials HD, releasing in the fourth quarter of 2010.

Along with 40 new levels created by the studio's professional level designers, Big Thrills will include 10 stages created by fans. RedLynx is holding a contest inviting gamers to submit their Trials HD stages for inclusion, promising cash, prizes, and in-game credit if their level is chosen for the expansion pack.

"Ever since we released the first Trials HD expansion, gamers have demanded more," says RedLynx creative director and lead designer Antti Ilvessuo. "They email us every day, they post on our message boards, and lately they've started calling my house and chasing me down the street. With this announcement, I can now emerge from hiding and get back to making games."
