The slicing kit from Synergy Blade‘s on the Unity Asset Store. Here!

Turbo Slicer cuts fast, repeatedly. In Synergy Blade we used it to slice bosses to bits on an iPad 1 at 60 FPS.

Turbo Slice includes demo scene with muffin slicing, complete with multitouch and glory trails. Add counters and game logic and have yourself a game, fast.

For more advanced work, you can call upon it directly to slice by a line in screen space, a plane as described by a triangle in world space or (for pro!) Vector4 plane equation in local space.

If you already have Turbo Slicer, you may download the demo sources for Unity 3 and Unity 4. This package includes both the slicing game demo and the sliceable demo.
