Released in 1990, Konami's Aliens arcade game arrived at a time when the company was at the peak of its coin-op prowess, having already delivered celebrated licensed titles such as Teenage Mutant Ninja Turtles (1989) and the original Contra (1987). The arcade market in 1990 was fiercely competitive, with beat-'em-ups and run-and-gun shooters dominating floor space, and Konami leveraged its technical expertise and the enduring popularity of James Cameron's 1986 film Aliens to craft a side-scrolling shooter that felt immediately familiar to fans of the franchise. The game is a side-scrolling run-and-gun that supports up to two simultaneous players, with each player controlling a Colonial Marine armed with the iconic pulse rifle. Players move through a series of stages that draw directly from the film's visual language — dark, industrial corridors, the colony on LV-426, and the Xenomorph hive — fighting off waves of Facehuggers, Chestbursters, and Warrior Aliens before confronting larger boss encounters. The controls follow a straightforward layout: a joystick for movement and directional aiming, a fire button for the primary weapon, and a secondary button for grenades or special attacks. Ammunition and power-ups are scattered throughout levels, encouraging players to push forward aggressively rather than camp in place. The level structure is linear, guiding players through increasingly dense enemy formations that demand both quick reflexes and cooperative positioning when played with a partner. Enemy attack patterns escalate in complexity as the game progresses, with Xenomorphs crawling across floors, walls, and ceilings in a manner that keeps players constantly scanning the screen. Boss encounters punctuate the end of major stages and require players to identify and exploit specific weak points under sustained pressure. Konami's hardware gave the game a rich color palette and fluid sprite animation that convincingly evoked the film's grimy, biomechanical aesthetic, and the sound design incorporated tense musical cues and weapon effects that reinforced the atmosphere of desperate survival. In its era, the cabinet drew strong attention in arcades due to its license recognition and the cooperative play hook, which encouraged pairs of players to feed quarters together — a proven monetization strategy that Konami had already refined with its beat-'em-up titles. The game was regarded as a competent and atmospheric licensed product that delivered on the promise of putting players inside the film's action, even if its underlying run-and-gun mechanics were not a radical departure from contemporaries. It stands as a representative example of Konami's early-1990s arcade output: polished, accessible, visually faithful to its source material, and designed to extract maximum play sessions from cooperative pairs.

About Aliens
What makes it special
Konami's Aliens is notable for translating the film's signature tension into arcade mechanics by having Xenomorphs attack from multiple vectors simultaneously — floors, walls, and ceilings — rather than simply charging from the right side of the screen. This multi-directional threat model, combined with two-player cooperative play, meant that partners naturally divided screen coverage between them, creating an organic teamwork dynamic that mirrored the Colonial Marines' squad tactics depicted in the film. The cabinet's visual fidelity to the 1986 movie's production design was also a standout achievement for its time.
Pro tips
- Prioritize Facehuggers the moment they appear — they move fast and low, and a single hit can cost you a life if you are focused on larger targets above.
- In two-player mode, assign one player to cover ground-level threats and the other to handle ceiling and mid-air enemies; splitting coverage dramatically reduces hits taken.
- Grenades are most efficient against clustered enemy groups at choke points — save them for tight corridors rather than wasting them on single targets in open areas.
- Learn boss weak points early: sustained fire on the correct location ends boss fights quickly and conserves resources for the stages that follow.
- Keep moving forward whenever possible — standing still causes enemies to spawn and accumulate behind you, making retreat increasingly dangerous.

Is Aliens arcade better played solo or with two players?
