I'll try describe it as well as I can remember:
First of all it's a racing game, I think it's for PS2, but might also be a PS1 game. It's relatively old (maybe 10 years even).
You can drive single-player, multi-player, arcade and some practice mode where you can get medals based on your time spent.
You can pick up power-ups such as homing missiles that target the player who is currently #1 in the race, you can also get turbo power-ups as well as stuff like single missiles. I remember something about teleport power-ups and possibly some kind of slows (this might be a different game).
The cars are quite flat so they can drive on both sides (meaning it can drive even if it's upside down=. I'd provide a screenshot but for obvious reasons I can't.
I really hope someone can help me find this lost game title
Thanks!
