A good cheat for beginners dat workz 4 me every time :)
1. Remove 4 small wheels and the battery.
2. Sell them both.
3. Buy 3 small wheels for better turning, and the better battery, you should have enough to buy a dagger.
4. Then when in a battle wait 4 them 2 come to you, and then use ur beta cornering to go around them and aim 4 the sides where there are no weapons :)
