So The Hero and his Ragtag Band of Misfits are storming your Evil Tower of Ominousness, your Evil Plan has failed and all you have left is your untried, unfinished Superweapon. In a last ditch attempt to stop the hero, your order the deployment of this weapon. . . "But Sir, it's not ready yet!" a random minion declares (this may be anybody from The Dragon, to the Bridge Bunnies). Foolishly, you ignore the warning, and deploy the weapon anyway, probably to disastrous results. The weapon can be anything; missile, Super Soldier, or in Fantasy settings, some kind of unstable magic.
