Effect: Increases perception
A drug in the gritty Max Payne series, it was originally created by the U.S. Government as a performance-enhancer for the military.
It soon became illegal and only available on the black market. This green liquid is injected via 'found' syringes, sounds safe enough. Side effects range from nausea to long and vivid hallucinations and a lot of slow-motion jumping.
Would be good for those of us in the real world that might be thinking about taking on organized crime in our day to day lives.
