Its VERY early access - nowhere near close to Wreckfest content :D
However, few things different:

- Sounds are nicer and you can hear whats wrong
- New damage system - suspension bent pulling your car to either side, you can get flat tires, tires can detach, or whole wheels, black or white some from damaged engines
- Seems more realistic damage model than before
- Car handling is grippier

DISCLAIMER
This is a chance for wreckers to drive an early (!) version of the game. For anybody who is expecting a fully-fledged, perfectly optimized game with several modes, dozens of tracks and vehicles, as well as an extensive career mode, please consider buying once we are releasing the 1.0 version of the game.

I love it, all the Negative reviews seem to focus on lack of content, I remember playing the first game in early access and it had 1 track but the final product ended up being awesome and this early release is way better than that, the physics , graphics and game-play are all improved, some people have no patience and want the game to be loaded with content from the outset for £20 quid, Let Bugbear do their thing, they know how to make the best Demolition derby style games, frickin loved Flatout 1 and 2, Oh and the wreckfest community was one of the best, If you don't like early access hold your horses and pay more for the 1.0 release in a year or two whilst I rack up killer lap times and skills.
