In all seriousness, I'd probably want to go old school and purchase a Thompson sub-machine gun with the 100 round drum magazine to start out with and a shit ton of box magazines afterwards.




If I wanted to be with a team, I'd probably bring a few of these with me:

Riot shield to block doorways and knock zombies out of the way while on the run.

Silencers for whatever weapons I plan to use.

M93 "Black Arrow" sniper rifle.

M249 Saw for cover fire.

Probably five Glock 17s with multiple 17 round magazines.

Two H&K MP5s, and multiple magazines, including two silencers.

That would work good for a four man team.
