Alien Shooter

About

Alien Shooter is a top-down action game where you play a lone marine fighting through an alien-infested research facility. You blast waves of enemies using a growing arsenal of weapons from shotguns to rocket launchers while managing limited resources and health. The linear levels mix combat with light puzzle elements as you navigate sealed corridors and activate security systems. Upgrades and power armor add gradual progression as you push deeper into the facility's core. The game gained a following for its fast-paced combat and replay value across multiple platforms including mobile devices. Two paid expansions added 10 levels and concluded the story about teleportation experiments gone wrong. With over 1.5 million copies sold across its lifecycle and still playable on modern systems through backward compatibility, it remains a niche pick for fans of old-school arcade shooting with RPG touches. The minimalist story and straightforward mechanics make it easy to jump into despite its 2003 release date.

Storyline

The player plays as a marine tasked to clear out an experimental laboratory where teleportation devices have allowed legions of aliens to pour into the world. The player has been given explosives to open up the sealed doors into these top secret areas; they had security measures in place so there will be stationery mini-gun turrets available to take them out. The government has given access to all the most advanced weaponry available in hopes of ridding the problem after receiving too many casualties of the previous military assault. A heavy burden is placed on one man.
