About Alien 3 (Video Game)

Alien 3 is a 1992 side‑scrolling run and gun game inspired by the film Alien 3. It was originally released on Sega Genesis and Amiga, and later on Super Nintendo, NES, Master System, Game Boy and other platforms. You play as Ellen Ripley, the main character from the Alien series, exploring the prison colony Fiorina 161 while trying to rescue prisoners and survive waves of Xenomorphs.

Unlike the movie, where Ripley has almost no weapons, the game arms her with a full arsenal: pulse rifles, flamethrowers, grenade launchers and hand grenades to take down Aliens and Facehuggers. The result is a fast, tense action platformer that mixes exploration, time limits and intense combat.

Story & Setting

The story takes place after the events of Aliens. Ripley’s escape ship crashes on the maximum‑security prison planet Fiorina 161, where a Xenomorph has begun hunting the inmates. In the game, you move through the dark corridors, industrial areas and tunnels of the prison complex, trying to complete missions before the timer runs out.

Each level gives you several objectives, such as rescuing prisoners, sealing doors, repairing systems or destroying alien eggs, before heading to the exit to advance. If you fail to save prisoners in time, you may see grim scenes of Xenomorphs bursting out of their chests.

How to Play Alien 3 Online

Playing Alien 3 on CraazyGames is easy and quick:

Open the Alien 3 game page and wait a few seconds for the emulator to load.
Press the on‑screen start button or the mapped keyboard key to begin.
Use your keyboard (or controller, if supported) to move, jump, shoot and switch weapons.

The game runs in your browser using emulation, so you don’t need any separate ROMs or emulator downloads.

Controls (Keyboard)

Exact controls can vary by emulator, but they usually follow a typical 16‑bit layout:

Arrow Keys – Move Ripley left, right, climb ladders, crouch and navigate platforms.
Z / X / A / S – Fire your weapon, jump, switch weapons or use grenades (depending on mapping).
Enter – Start / Pause.
Shift / Backspace – Open mission terminal or additional actions in some versions.

If the default controls don’t feel comfortable, open the emulator settings (gear icon) and remap keys to your preferred layout.

Gameplay & Missions

Alien 3 combines run and gun action with mission‑based objectives on large, maze‑like levels.

Use your motion tracker to locate prisoners and nearby Xenomorphs.
Rescue all prisoners in a level before time runs out, or they will die.
Fight Aliens, Facehuggers and eggs while managing your ammo and health.
Find the exit once objectives are complete to move to the next stage.

The Sega Genesis version features around 15 stages, while the Super Nintendo version includes 6 larger mission‑based stages, each with different objectives and layouts.

Weapons & Tools

Ripley is much better armed in the game than in the film.

Pulse rifle – Fast, automatic fire for dealing with groups of Aliens.
Flamethrower – Very effective at close range and against Facehuggers.
Grenade launcher & hand grenades – Great for tight spaces and tough enemies.
Motion tracker – Shows enemy and prisoner locations so you don’t get lost.

Tips for New Players

Watch the timer – You must finish your objectives before time runs out, or prisoners will die and you’ll fail the mission.
Use the motion tracker often to avoid wandering aimlessly in the maze‑like levels.
Save flamethrower ammo and grenades for tight corridors and groups of Xenomorphs.
Move carefully; rushing ahead can spawn enemies before you are ready to fight them.
