Shaun of the Dead versus Zombieland...
The Zombieland crew (Tallahassee, Columbus, Wichita and Little Rock) versus The Shaun of the Dead crew (Shaun, Liz, Ed, Dianne and David.)
Shaun and his people have made their way to the Winchester, seeking refuge from the zombie horde. They notice a black SUV parked outside. As they enter the pub, they see Tallahassee and his people sitting at a table. The Zombieland crew, as it turns, has run out of ammo and supplies and has decided to claim the Winchester as their safe haven.
Shaun knows there is only enough supplies for 4 to 5 people, so does Tallahassee, as do the others. A fight to the death ensues.
No guns, h2h combat only, and whatever they can get their hands on from inside the pub. Tallahassee left his weapons in the SUV. There is no ammo for the rifle above the bar.
Who is left standing in the end?
