Would you rather fight zombies with a Call of Duty Ray Gun, or a Portal Gun?

The Portal gun would definitely be the best because you could get out of the shitty scenario that is having to fight (presumably nazi) zombies, or you could just send them sixty feet in the air, watch them fall, and then step back when the dogs get there, so you can make them fly into each other. It's really just an all purpose tool.

Portal Gun, I'd just teleport onto a table and then create one portal on the ceiling and one under the zombies, then quickly do one on the floor under the ceiling and keep them there for eternity

Portal gun. 1. Shoot portals underneath 2 different zombies to have them collide into each other, and fall forever. Also, teleport around to get away.

Ray gun for practicality but portal gun for the lulz so ray gun
