Gate Crasher

Somewhere in the future, technology has advanced to a stage where citizens can enhance their brain functions by installing electronic implants inside their heads. Millions of people have undergone surgery as a means to become mental superhumans. As it turns out, these devices are actually a method of mind control for the corporations to affect how people think and act. You are a gunman who's had enough of that. Your job is to infiltrate the headquarters of one such corporation and assassinate the chairman and orchestrator of this conspiracy.

Gate Crasher is a first-person shooter, not unlike Wolfenstein 3D. You wander through the halls and corridors of a five-story office building, armed with a firearm, taking out armed henchmen in black suits and making sure not to hurt innocent programmers (Dressed in white shirts). There are bullets and first aid kits strewn about the complex, to replenish your ammo and health. Also, there are electronically locked doors whose code must be decoded (In some sort of puzzle minigame) and computer terminals to destroy before you can move to the next floor. Technically, the game features 360 degree motion and digitized sound effects.
