Dirt Showdown: Slam and Sprint Challenge

How does the game Dirt Showdown: Slam and Sprint Challenge work?

Today's engine game won't be simple car races, but it has lots of fun new stuff: the races on the track will involve lots of skidding... so be really careful not to crash into the guardrails! The best part of the game is the demolition mode in which you'll find an arena and you'll have to pray that they don't destroy you...
