Alien Survival is a free online 3D arcade shooter where you play as a stranded astronaut fighting off waves of aggressive alien creatures on a mysterious planet. Your rocket engine failed on landing, leaving you exposed and vulnerable. Your only way home is collecting enough resources scattered across the planet surface — but those resources are guarded by relentless hostile beings that won't negotiate.

The gameplay keeps you on your toes as creature hordes swarm from multiple directions, forcing you to stay mobile, aim fast, and prioritize targets. Resource collection adds a layer of strategy — do you push deeper into dangerous territory for bigger hauls, or play it safe near your landing zone? The 3D visuals give you real spatial awareness of incoming threats, making every encounter feel genuinely tense. Casual in format but demanding in execution, the game rewards players who learn enemy movement patterns and manage their positioning smartly.

If you enjoy free online alien shooting games, casual 3D arcade games, or space survival challenges, Alien Survival hits that sweet spot between accessible and genuinely challenging. It's a great pick for fans of wave-based shooters, sci-fi arcade action, and quick-session survival games you can jump into without any download or install. Perfect for browser gaming on a lunch break or an extended session grinding for that final resource count to unlock your escape.
