Alien Shooter

Top-down shooter where you're a lone marine clearing an overrun research facility. Teleportation experiments went wrong, flooding corridors with alien swarms. You blast through sealed lab sections using explosives to breach doors, grab military-grade weapons scattered throughout, and set up stationary turrets at choke points. Levels throw waves of creatures at you—expect hundreds on screen. The core loop: shoot, loot better guns, survive the next room. Two expansions (Fight for Life, The Experiment) add ten missions total and wrap the story. It's straightforward arcade carnage with a sci-fi disaster premise. No stealth, no puzzles—just crowd control and firepower management. Works if you want pure reflex shooting without narrative fuss.
