Crash-landing on the hostile surface of Azarin 2E, Alien Breed: Tower Assault drops you right into a swarm of territorial xenomorphs with barely enough ammunition to reach the first Intex terminal. Developed by Team17 Software Limited, this 1994 overhead shooter built a brutal labyrinth where picking the wrong doorway can end your run long before you ever reach the queen.
Stepping off the dropship into Azarin 2E
You hit the ground running the moment your marine steps out of the wreckage. The atmospheric defense lasers have shredded the invasion fleet, leaving rookies Nash and Jordan as the only survivors on the surface. If you play solo, the game subtly accounts for the missing second player by establishing that Jordan died during the crash landing.
The top-down perspective forces you to check every corner of the screen before moving ahead. Shadows hide patrolling beasts, while laser turrets and automated landmines lie in wait along narrow metal corridors. Within three minutes of starting, your default sidearm feels completely inadequate against the swarming horde.
Survival depends entirely on finding an Intex Networks console. These wall terminals act as the local black market, letting you trade hard-earned credits for heavier guns, extra keycards, and fresh stock of ammunition. If you drain your funds on the wrong gear early on, the later sectors become an absolute nightmare to clear.
Branching pathways turn Alien Breed: Tower Assault into a maze
Unlike standard linear top-down action games, this campaign spreads across open outdoor sectors and connected multi-level facility towers. Depending on which exit airlocks you choose, there are 276 potential paths to complete the game. You can explore a variety of distinct zones throughout the facility:
- Crash Landing Site and open Civilian Zones near the surface
- Stores and Engineering Sectors packed with hardware and power nodes
- Heavy Security Zones guarding access to Military Sectors
- The central Main Tower where the ultimate threat resides
This layout gives you genuine freedom in how you tackle the invasion. You might clear out the Civilian Zones for extra cash or head straight through the Military Sectors to hit the Main Tower early. Somewhere deep in the complex, you have to locate the alien queen, trigger the facility self-destruct sequence, and sprint back to an escape point before the whole base detonates.
Backpedaling into danger and the problem with retreat mode
To give players a fighting chance against fast-moving enemies, the designers added a dedicated retreat key. Holding this button lets your marine back away while maintaining fire in the opposite direction. It sounds like a great tactical tool on paper, but the execution turns out to be notoriously tricky under pressure.
The control system frequently gets your character locked facing the wrong direction during a quick retreat attempt. Instead of laying down cover fire while stepping back, you suddenly find yourself backing directly into an alien bite while shooting aimlessly into an empty hallway. That single control quirk caused immense frustration among players, and magazine reviewers picked up on it immediately.
When the game arrived on store shelves, magazine scores split sharply over these mechanics. PC Gamer and PC Zone both awarded the PC version a solid 75%, appreciating the tense atmosphere and sampled audio effects. Meanwhile, Computer and Video Games handed down a harsh 40% rating, largely put off by the punishing difficulty spikes and clunky backpedaling movement.
How the PC conversion brought Team17's shooter to DOS
The original project began development under the working title Ravager before settling into the established franchise line. While Team17's core creators Rico Holmes, Andreas Tadic, and Peter Tuleby designed the base game under producers Martyn James Brown and Gavin Wade, porting duties for the PC release fell to East Point Software and Promethean Designs.
The technical team crafted a solid conversion for MS-DOS hardware. Nigel Taylor handled the PC audio conversion, giving the gunshots and screeching monsters real punch through standard sound cards, while Chris Hare, Nik Love-Gittins, and E. Mark Smith adapted the PC visual assets. Players who bought the full CD-ROM package received live-action full-motion video intro sequences, though these movie files had to be omitted entirely from the standard floppy disk boxes.
Running the original release directly on modern systems often leads to modern graphics timing glitches and instant system crashes. Fortunately, browser-based emulation handles the precise engine speed requirements without requiring custom environment tweaks.

If you want a tough sci-fi challenge that demands actual spatial awareness, this entry in the series still hits hard. Crisp sampled sound effects and heavy visual shadows make the oppressive atmosphere feel properly lethal in every dark corner. I still find myself holding my breath every time an Intex terminal screen closes and places my marine back in an unlit hallway.
