Set of 3 new Monsterball levels from D3's creators. These are small levels, good for fast-paced games with few players. Snake Eyes is a single twisting tunnel. Crossfire is good for Anarchy as well: the two teams are separated and can only snipe at each other or the ball. And Circuit Breaker has unique goal loops that let you defend your goal in new ways, or score on your enemy from two directions. These are meant for Monsterball, but also work with other game types.
Crossfire is almost like a new hame, fighting long distance with guideds and MD. Circuit Breaker is the ultimate Monsterball level, far more fun than the popular Veins which I find too big and slow. If you've never tried MB, Mayhem 3 will hook you.
