rocket slime is a great game for the ds. its a lot different from the rest of its series, which isnt a bad thing.
The Good: Tank battles are awesome, tank masters adds replay value, lots of tanks to unlock, basically anything you can pick up in your tank you can fire at the enemy alchemy is cool, lots of different kinds of ammo, u can have a crew for your tank which is a vital part to winning, u can have a lot of ammo in yourr tank at a time.
Bad: Music gets repetitive, slimes jokes are gay, not enough monsters, u cant unlock the angel tank (dammit)
All in all, a great game
