The Lawnmower Man is the game based on the 1992 movie of the same name, starring Pierce Brosnan as 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 in the process he is given a forced vacation, and while taking notes on the need for 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 stopped the experiments, The Shop, a secret agency overseeing Project 5, reinserted the drugs responsible for violent behaviour into the program and sped up the treatment.
The gameplay involves platforming as the player takes 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 game features true-3D level connectors based on the CG sequences of the movie.
The gameplay involves four different modes: Virtual World, Cyber War, Cyber Run, and Cyber Tube. Each mode takes a slightly different approach, with varying objectives and obstacles to overcome. The player must navigate through levels at high speed, avoiding obstacles and occasionally shooting enemies in order to progress.
