Batman, Master Chief, and the Doctor vs Black Ops Zombies

 They are in the Black Ops level "Five". They have one hour prep before the zombie waves start coming. How long do they last, or do they escape.

Batman has his normal suit and gear, Chief has an assault rifle, halo 1 pistol and plasma grenades, Doctor has sonic screwdriver.
They all have access to the normal guns and perks and equipment in the level. They are not affected by the scientist who takes guns.
Chief is bloodlusted against the zombies, but will still help his comrades, Doctor is trying to escape with his comrades but will help fight if necessary, Batman is trying to escape and fight at the same time. Also, the tardis is parked outside, if they can get to it.

Normal physics apply. So if a grenade launcher can't punch through a wall in black ops, it can here.

I doubt the zombies are getting through Chiefs armor, so he survives.

Chief bloodlusted and has the Halo 1 pistol? He doesn't even need the others. Black Ops zombies get demolished.
