Its the prequel to Wreckfest and you can tell right away. And thats a good thing, game is awesome arcade-y racing fun.

Flatout, Burnout & Stuntman used to be my favorite games back then, games like these never get old

The game is a significant upgrade to the hit game FlatOut 2.
Beside the already existing trophies in the Flatout mode, you now can play extra challenges in the new arnage mode.
Some cars previously available through the Flatout mode now are behind the arnage mode missions (f.e. Road King, Insetta), however new cars like the Grinder have been added too.
Cars available through cheat codes can be unlocked after reaching gold in arnage missions featuring them.

The physics have been overall improved and driving feels a lot smoother compared to the original.
Textures have been improved as well, however the HUD is still in the old resolution.
This can be fixed with the new workshop implementation.

The only real negative about the game I can tell is the OST.
The original had a much greater selection that also felt more appropriate, but people have already uploaded workshop mods adding the original OST and more custom songs to the game, so the issue is easily solved.

Definitely one of the best racing games out there, being a solid rival/competitor to the beloved Burnout series.
