Other points of interest
To the left of the start is a hallway with six windows, each containing a Commander Keen and a shoot-to-activate switch. However, at the start of the level only one Keen is open to kill; the other 5 must be opened by finding and killing 5 more hidden Keens scattered throughout the rest of the level.
Once the player has found (and killed) the five hidden Keens and activated all 6 switches, the chamber at the end of the hallway will open. Inside is a teleporter to a secret chamber with a "thank you" message from the developers and a list of level design and music credits, as well as three Supercharges.
- From the map start, exit the cave to the east. Enter the room in the south of this area and exit it through the western door. Outside, turn to the south again and enter the next door. Strictly go south past the lava "pool" to an arachnotron on a platform (that is in the east of the invulnerability sphere and a invisibility sphere). The wall east of the arachnotron has a baron's face on it. Lower it to find a blue armor.
