Ok, well Motor Kombat is not that hard. If you play racers you'll get the hang of it really fast.

Just pick your racer, go online either host or opti-match. Pick your driver and try to win the race.

The green lightning bolt icons are power boosters, run over them and you'll go faster.

Coins for the krypt are pointless unless you need to unlock stuff then go for them, otherwise ignore them in racing.

Also, the yellow icons those are your specials which every racer has. They're all different then others.

R is accerate, L is brake or R=go and L=stop/slow down

A is your power up move use it wisely racing and it can lead you to victory.

I'd practice offline first personally with this mode before going online.

Now, if you want help with MK the fighting mode what do you want to know exactly?

Basics, which characters are better, KAK tips, online play, comp online? What?

There's also others here besides myself that I'm sure wouldn't mind helping out also.
