Trials HD: BIG Pack track preview [UPDATE: Achievements, more!]

The first DLC for the massively popular Trials HD, dubbed "The BIG Pack", is set to launch on December 30th (despite rumours of an earlier release) [update: we're back to the 23rd, and this is "official" .. apparently] for the affordable price of 400 Microsoft Points. The DLC will have 23 new courses which focus on the Medium and Hard tiers.

Developer RedLynx have released a new trailer previewing some of those tracks today:

Update:

Achievements!

-Piggyback (15G): Catch a ride and surf on top of a car in Dangerous Ride. Can you go the distance?

-Ride on top of a car in Dangerous Ride DLC track.

-No Deal (15G): Which box to choose and when to bailout?

-Bail out and land the rider inside a lucky box.

-Look ma I can fly! (20G): Bounce 5 trampolines in succession in Skyway to reach new heights.

The DLC also comes with an update which includes:

- Ultimate Endurance tournament simplified. This change makes the close to impossible Marathon achievement possible for much wider audience. The tournament now includes beginner/easy/medium tracks.

- Improved Down the Stairs skill game. The physics glitch all top players used is fixed and now the user has better control over the tumbling down rider.

- Fixed the corrupted leaderboard scores found in some tracks (zero times, impossible scores). All leaderboards have been cleaned off corrupted scores and we have a system in place to keep them clean in the future as well.

- Fixed a number of minor bugs reported by players and found by testers. Now the game is even more polished and stable than before.

Due to huge demand, the amount of tracks users can save in their hard disks and memory cards is doubled.

You'll also be able to nab an avatar clothing pack and premium theme soon.
