Part 23

Jump across platforms, avoiding spikes, and encounter red slimes.

Bring a slime with you to push past low spikes hanging from the ceiling by ducking.

After crossing the spikes, break free and ascend platforms. Avoid using a slime to descend the next column due to spikes at the bottom; descend carefully yourself.

Swing over the box to reach the contact room door.

Enter the contact room (highly recommended for a time-saving trick).

To cross the spike pit with a hovering platform: The hard way involves shooting your arm into the low ceiling, swinging back and forth, and timing your jump to the platform when it's close. The easier way: Leave the contact room, IMMEDIATELY shoot your arm into the low ceiling, and swing left, letting go. This times your swing with the platform's movement from the far left.

While riding the platform, duck under low spikes and then shoot your arm into the last clear part of the ceiling to swing to safe ground. Avoid clumsy and risky ground entry from the elevator.

Proceed left to an area that looks like an acid bath; the red substance is background. Drop down and go to the bottom.

Avoid mini tanks raining from the roof and move left.

Climb the high platform column to reach the boss room.

BOSS FIGHT: Guard Robot: Use the Rocket Launcher to defeat the Guard Robot with one shot. Quickly spray the final computer with shots before it can attack you.

Proceed to Area 11, Level 11 - The Fire Plant, an enemy base requiring an Orange communicator and awarding a Bullet-Proof Vest. The difficulty is rated as Horrible.

The level begins with a swinging challenge over fire pits. Swing from the roof, starting at the edge of the fire pit and swinging right. Shoot the next arm at the peak of your jump for the longest swings. After 4-5 long swings, you will reach a high platform. If you land on a platform just above the fire, you must go back.

Go right, kill the fat guard, and keep going right.

Drop down onto a spring board platform. Be ready to shoot your arm into a high platform to avoid being bounced into the fire pit.

Drop onto the platform with the spring board on the other side and go right.

Go up to the platform with a patrolling mini tank and destroy it.

Ascend the long platform with three spring boards above you.
