currentammo: amount of damage for each contact. (default 10)
speed: speed that it will follow it's path. (default 10)

Use the angle buttons to point the buzzsaw in the direction it
should face.

Place on a monster path if you want it to move.

If it is targeted, it will wait until triggered to activate.

It will not damage players until activated.
