Bloodlust Zombies (2011)

Scientists devise a chemical for use in war that causes enemy soldiers to kill each other, thus eliminating the need for our troops to risk their lives.  The problem is the scientists have been so focused on their task of creating a killing machine, that they never devised a way to stop them once the enemy is dead.

An accident in the building unleashes the toxin and the building goes into lock down.  Although the lab has  just celebrated the success of the serum - with champagne in blue plastic flute glasses -  once it is released in the building their reaction is, "God help us."  So maybe they should have done better work since accidents and sabotage are always possible.

For a lab that does secret government projects like this, they have a terrible security system.  In order for the doors to be released from lock down (security can't override it), they need to shut off the power to the building, then turn it back on and reboot the system which takes twenty five minutes.  Security has to check the doors to make sure they are locked and no one can get out until the system reboots.  Strangely everyone panics when the lights go out, even though there was just an announcement that the power was going to be shut off.

When the accident occurs,  several people in the isolation lab become infected and begin killing.  Since no one can get out of the building, the virus starts spreading.  A temp worker who just arrived for her first day of work convinces security to let her into the control room and then proceeds to verbally rip the guard apart.  She is the most annoying character.  Everyone watching the film hated her and wished she'd die. It's the only film I can think of where you want people to stop helping the annoying asshole character.  So we all cheered when the guard pushed her out of the safe room. Yay!

Also of note is that Alexis Texas is a porn actress, so that tells you the quality of the film when she's listed as the selling point.
