Darkness Restricted

You are loaded in a simulation that will test and optimize your handgun combat skills. You have to find a USB key and plug it in the laptop of the level to move up to the next one. These areas will be loaded with enemies using night vision goggles in complete darkness. Your only way through the obscurity is your flashlight with limited battery. The main goal is to finish the simulation as fast as possible to have a chance to put your name on the leaderboard.
