Visible crew/equipment: During the fight between the Rippers and the guards at Water and Power, you can see the stunt wire attached to one of the Rippers.

Continuity: When Rebecca makes her boyfriend strip, you can see the gun's laser on his hand before she comes around a corner and points the gun at him.

Continuity: The Tank alternates between having a silver machine gun to not having one, to having an Uzi 9mm, to having a 40 caliber.

Audio problem: When Rebecca is filling up her tank gun with beers, you hear her voice but her mouth doesn't move.

Continuity: When the Water and Power boss first sticks the water-sucker into his captain's back, and lets him fall to the ground. He pulls out the device once it's full and walks across the glass-ridden floor, drinking from the bottle. When he pulls out more than just the bottle, it looks like all but the needle-suckers stuck in the captain's back, but in the next shot it's just the bottle. He didn't have time to detach the bottle and get rid of the device.

Continuity: In the scene where Lori is shoved down the pipe, check out the close-ups as she slides down. At least twice she has one blue eye and one green eye - though her eyes are blue in every other scene.

Plot hole: All of Keslee's troops are spit and polish with nice uniforms, holsters and boots. But in the scene where Becca is pulled out of the pipe, one of them just happens to have a pistol in his belt for Keslee to grab and threaten Becca with. Very convenient.

Continuity: Lori had two stolen tanks to convert - a Russian T-55 and a PT-76. The outcome of this conversion is a M3 Stuart with a turret from something bigger - Sherman Firefly or M60. Better than McGyver.
