Released in 1981 by Williams Electronics, this classic side-scrolling action shooter brings the frenetic arcade experience to DOS. Building on its legendary predecessor, the sequel introduces new survival mechanics like teleportation gates and cloaking, demanding quick reflexes and constant situational awareness as you defend humanoid populations from alien abduction.

How to play

The objective is to destroy waves of alien landers and mutants while preventing them from carrying your humanoids to the top of the screen. Use the arrow keys to maneuver your ship over the terrain. In most DOS setups, your primary fire, thrust, and reverse controls map to the Space, Ctrl, and Alt keys, with Enter used to start.

Tips

Fly through the Stargates to instantly travel to humanoids in danger.
Use the Inviso cloak sparingly when surrounded, as its energy is limited.
Prioritize shooting alien landers before they capture a humanoid, as dealing with the resulting fast-moving mutants is far more dangerous.
