Play CORRIDOR 7: ALIEN INVASION - Shareware Version Online – MS-DOS Game

Game Overview

Step into the boots of a lone marine in CORRIDOR 7: ALIEN INVASION, a classic '90s FPS that throws you into a claustrophobic, sci-fi nightmare. Armed with an arsenal of weapons, you'll blast your way through maze-like corridors swarming with relentless aliens—think DOOM meets Wolfenstein 3D, but with a darker, more isolated vibe. The shareware version gives you just a taste of the chaos, teasing you with tight level design, eerie sound effects, and that addictive, old-school run-and-gun gameplay that keeps you glued to your CRT monitor.

What makes CORRIDOR 7 stand out? It’s unapologetically tough, with enemies that ambush you from every angle and puzzles that’ll test your reflexes and your brain. Sure, it might not have the polish of its bigger-name cousins, but there’s a raw, nostalgic charm to its pixelated violence and tense atmosphere. If you miss the days when shooters were all about fast action and zero hand-holding, this hidden gem is worth dusting off your DOS emulator for.
