my ORANGE TRANSPARENT CHAINSAW rules are:
Orange transparent chainsaw
Damage: roll 1d6, the result is the number of bricks it can destroy.
When droped it will de activate and will not destroy anything untill its picked up.
oh and the chainsaw launcher would be a normal launcher.
the payload would be just the chainsaw stats.
