Gex: Enter the Gecko/Frankensteinfeld

Frankensteinfeld takes place in a small haunted mansion. You start in a small room, where you can jump onto the wall hanging from the ceiling to collect some skulls, and where the exit is guarded by a single pumpkin.

After entering, and going through the first door, you are in a circular room with two other exits. Moving to the left leads to an open outside area, while the right leads to a more enclosed second room with the electric floor.

Run the Axe Gauntlet
In the central room, take the door left of the entrance. Turn to the left and climb the ramp, move past the zombie and hazards to the end. A second ramp leads up, with easily dodgable skulls bouncing down. Turn left, and move past the statue dropping the axe. At the end of this path is a zombie - attacking it detaches the head, which must be itself attacked to destroy the zombie and collect the items.

Climb up, and turn left across the pentacle platform. Turn right, and past the skull-thrower is a series of three statues dropping their axes. The door at the end leads to the red remote.

Head down the Ramp
In the central room, take the door to the right of the entrance. If you want invulnerability, you can jump onto the platform, and across the platform and chandelier to reach the other side of the gap. Clime the wall on the other side, where one of the branches leads to a platform where you can smash a TV with a red bug.

In this room, you can slide down the green ramp, turn left until you reach ground, and climb the stairs. There is a ramp leading upward where you see two axe-statues, terminating in a climbable wall. When you climb to the ceiling, you should find a gap which you can crawl through. Jump down and proceed through the double doors.

Jump and splat the pumpkin and slide down this ramp. The end of the room has a platform leading to a clock, and a series of platforms (starting on the right) which you have to climb. This will lead to the central remote room, where you can get the second remote.

Stick to the Ceiling
In the central room, take the door left of the entrance. Proceed to ascend in the same way as the first task, except you turn right when you reach the pentacle bridge. Approach the end of this pathway to see a platform on the right next to the statue. Jump across the gaps and splat the pumpkin.

The right turn leads to a platform, and two chandeliers. You will need to jump across these quickly, as the chandelier will drop if you wait too long on it. This route eventually ends at a climbable wall. Climb the wall to reach a maze on the ceiling - aside from a few minor collectables and enemies moving back and forth, there's nothing of interest here. The exit is on the right, and can be reached by taking a right at the first branch, a left, then a right.

In the next room, perform a running jump across the gap.

Past the door is a connection to the remote room. Walk along the platform, being careful not to fall, and you should retrieve the third remote.
