Alien Hunters is a stealth game with a simple, satisfying loop: enemies patrol a level, you move behind them unseen, and a single strike from behind takes them down. Get spotted from the front and it's you who goes down instead.
It plays as a puzzle rather than a fight — reading patrol patterns, finding the moment when two guards are facing away from each other, and moving between cover. Missions escalate by adding more enemies and tighter sightlines.
Approach from behind. A strike from the rear takes an enemy down instantly; being seen from the front is fatal to you, so positioning is the entire game.
No — it's stealth. You can't win a straight confrontation, so the challenge is reading patrol routes and timing your approach.
Yes — tap to move. Nothing to install.
