Commander Keen 2: The Earth Explodes is a classic DOS action platformer developed by id Software in 1990. Picking up right where the first episode left off, Keen must navigate through various alien cities on a Vorticon mothership to disable the weapons targeting Earth. The game expands on the original with new environmental hazards like light switches that toggle platforms and deadly security robots.

How to play

Your objective is to find and destroy the ship’s Tantalus Rays scattered across different levels. Use the Arrow Keys to move, Ctrl to jump, and Space to fire your raygun. Once you find it, use Alt to activate your pogo stick, allowing you to reach higher areas.

Tips

The pogo stick makes you bounce continuously, so time your horizontal movement carefully to avoid landing on hazards.
Watch out for the purple Vorticon Elite guards; they are fast and can jump between platforms just like you.
Light switches not only illuminate dark areas but also toggle the collision of certain platforms, requiring you to memorize their positions in the dark.
