The Lawnmower Man is the game based on the 1992 movie of the same name, loosely based on a Stephen King short story. The game follows Dr. Lawrence Angelo, a scientist working for Virtual Space Industries in "Project 5", a secret research that attempts to increase the intelligence of primates using psychotropic drugs and VR training.
With his reluctance to aim the research to military purpose, after one of the chimps escapes and shoots a guard, he is given a forced vacation. While taking notes on the need for an experiment with a human subject, he notices Jobe Smith, a simpleton who makes his living on odd jobs such as mowing the grass. The first experiments quickly increase Jobe's intelligence, and while after an accident Angelo stops the experiments, The Shop, a secret agency overseeing Project 5, reinserts the drugs responsible for violent behaviour into the program and speeds up the treatment.
The gameplay involves platforming action, with the player taking control of Dr. Angelo or Carla Parkette in typical side-scrolling shooting action. The player can collect better weapons or data discs, which after collecting a number of them allow to morph into the Virtual Suit, giving protection against a first hit.
The twists of the game are true-3D level connectors, based on the CG sequences of the movie, usually involving avoiding obstacles and shooting at high speed in the VR world. There are four different modes: Virtual World, Cyber War, Cyber Run, and Cyber Tube, each taking a slightly different approach to gameplay.
