An ink pen?
Toothpaste tubes?
A distracting penny?
Clusterbomb of raisins?
An Apple that shoots worms?
A Hammer that fires rockets?
A cube that takes out the enemy's eye?
A ray gun that very slowly causes cancer?
An XBox, that you drop from a higher level?
A bulky, futuristic laser cannon that fires bullets?
A bucket of water with which to soak the unexpecting foe?
A gravity sucking thing shaped like an open-doored Tardis?
Ham slices with which to slap the face of hostility in ironic mocking?
A flamethrower that requires rubbing together two sticks to create a flame?
Turrets which shoot each other in the hope of catching the enemy in crossfire?
A gun that fires a cup, a kettle, milk, a teabag, and a spoon, in that order in a cycle?
A large Cola bottle that you shake up, then loosen the cap of, hurl, and run away from?
If your game involves at least half of these...
Shove your shitty MMORPG idea and get me a drink.
