Mesh collider cost

Hi there,

I'm creating a 2d melee game, star control style, and wondered if mesh colliders for the 2-4 players (and sphere/capsule for everything else) would be too expensive for the iphone? Are there any other drawbacks with mesh colliders that I should be aware off (e.g. will it make a bounce unpredictable when colliding with some other mesh?)

Thanks Mike

Is there any reason for using mesh colliders? Typically, dynamic objects use primitive colliders, or compound primitive colliders if a single one isn't accurate enough.
