How it plays
How does Commander Keen: Invasion of the Vorticons play?
The game uses a side-view platform perspective. Keen travels across an overhead map, selecting stages and occasionally finding optional routes, while each level contains platforms, hazards, enemies, ammunition, and valuable items.
The objective is to reach the exit of each stage, survive contact with Vorticons and other creatures, and collect points and lives. Keen can run, jump, shoot, and use his pogo stick to cross difficult gaps. Completing levels advances the episode, while secret areas and bonus objects reward careful exploration.
Plan your run
What is the best way to play Commander Keen: Invasion of the Vorticons?

- Explore side passages for ammunition, extra lives, and bonus items.
- Save shots for dangerous enemies and use the pogo stick carefully near ledges.
- Check the map for routes that avoid unnecessary hazards.
