perform other, situation-specific actions, such as rocking a cage back and forth. In the initial part of the game, the player's character Lester is unarmed. He is able to kick at small creatures, but is otherwise defenseless. Later in the game, the player acquires a laser pistol from a fallen foe. The pistol has three capabilities: a standard fire mode, the ability to create force fields to block enemy fire, and a powerful charged shot that can break through force fields and some walls. Enemies also have the same capabilities, requiring the player to take advantage of the three gun modes and the environment to overcome them. Lester and his alien ally cannot sustain any damage, and the game ends immediately if either of them is struck by a projectile or comes in contact with an animal or an environmental hazard. However, the game uses numerous checkpoints enabling the player to keep restarting at the last point indefinitely. On the Amiga and older consoles without the ability to save a game, the player can write down an alphanumeric code for these checkpoints and re-enter it when restarting the game later. In any given scene, the game provides no clues as to what the player should do next, features no HUD except for an oxygen bar during the swimming sequences, and no on-screen text; and the characters the player meets speak in an unintelligible alien language. Plot The protagonist of the game is Lester Knight Chaykin, a young physicist. In the opening cinematic, Lester arrives at his high-tech underground laboratory in his Ferrari 288 GTO during a thunderstorm and goes to work on his experiment using a particle accelerator, attempting to reconstruct what happened when the universe was born. Immediately before the particles reach their intended destination, a lightning bolt strikes the laboratory and interferes with the accelerator, causing an unforeseen particle fusion and an explosion, opening a hole in time and space and teleporting Lester to a barren, alien planet. After evading a number of dangerous indigenous animals, Lester is captured by a race of humanoid aliens and taken to a subterranean prison camp. Lester escapes along with an alien captive known as "Buddy" and the two must evade capture while travelling through a series of dangerous environments, battling alien soldiers and wild creatures while solving numerous puzzles in order to survive. The duo traverse the prison complex, a cave
