What level does the winner start on

The fighting style is similar in feel and speed to Street Fighter, but features character-swapping and character bouncing off the edges of the screen like Tekken Tag. Also like Tekken Tag, if one of your team members goes down, you lose the fight, even if your other teammate had full health. The fighting is all done on a 2D plane like Street Fighter, however.

Check out the video review at GameTrailers as they comment a lot about the engine itself.

You're supposed to destroy all of the stationary targets before your tank is immobilized. You can only start firing once you approach the firing line (indicated by a red line) at a 90° angle.

You get one point per target and you can get them in any order. If the score goes over 52, it will wrap around and go back to zero. The score will also reset if you move the tank over the mine field, and then you can start all over again until the game time runs out.

If you hit 10 or more targets, you get to play a bonus round after the regular game time runs out and its score will be added to the overall score of your game.
