How to unlock the Battlemaniacs achievement in Battletoads - Definitive Guide
This achievement is obtained midway through level 4 (the theme park). Obviously, you could just battle through level 1 repeatedly, but level 4 has a good density of enemies, and since you are likely going through all achievements anyway, you will get this in level 4 as you play through the game.
