Score indicator glitch
Not really a helpful glitch, just something I found. okay, if you score a point right before you get blown up, when you respawn, the point indicator remains huge.

How to get high scors easy
I found a way to high scores easy.

1. when you race a death race dont let go of the fire button. eaven if you dont have a good shot you can be srprised.

2.while you are doing a death race you all wase want to turbo as much as you can. you can kill for tuching then.

3. when you are doing an artifact race do turbos and power slides it helps.

4. speeking of artifact racing firing is not important defence is alwase have
red eago with you.

5. also while doing an artifact race put a bomb when you get an artifact.
some times the artifact go to the same spot.

ps please write to me if you need help I know everything about it
