RedLynx has released details on its upcoming expansion pack for Trials HD, called Big Trills.
Slated for release this fall, Big Thrills will contain 40 new levels, and 10 user-created tracks to be determined through a contest.
"Ever since we released the first Trials HD expansion, gamers have demanded more," said Antti Ilvessuo, the game's lead designer and creative director of RedLynx.
"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."
Those who think their track has what it takes to be included in the game, can also win up to $5K in prize money and everyone whose track is included will also receive in-game credit.
"We're thrilled - no pun intended - to present this contest with our partners at Microsoft," said Tero Virtala, CEO of RedLynx.
"We couldn't think of a better way to give back to our fans than to give them the opportunity to have their work featured right alongside ours in the next expansion of the legendary Trials HD game."
