Tremor:

Fight Tremor by dodging his projectiles and attacking with combos when you have an opening. When you get close, he will pound the ground; endure this and continue attacking until he is defeated.

After defeating Tremor, walk through the portal. You will have a conversation with Gemini.

You will arrive in the Outworld, the final level. Your objective is to find two stones for the altars of King Kang and King Tsung.

Head forward, then left, and kill the guards. At the very end of this area are the altars of King Kang and King Tsung.

Head back and go right. Kill the two enemies there. An easy tactic is to use the Super Uppercut combo to knock them off the edge.

Go down towards the purple lighting to find a portal. Enter it.

Go left, then up to get shotgun cartridges.

Go to the center to receive a stone called the Dragon Eye.

Go back and head left to a platform. You will find a medium medipak and a portal.

After going through this portal, head left, then up to get some rockets.

Go back and head right. Near this right is a chance to go down; do so carefully to avoid falling.

When you can't go down further, go left.

When you reach a square platform, go straight and continue straight into the red portal.

You will land on a purple polygon figure. Go straight, then go left.

When you reach a square, head down and watch your step. On your left is a series of squares that are not aligned properly. Try to stay in the center and walk straight left, aligning yourself with the next block. Diagonal steps can also help. If you fall, you may land on green turf that leads back to the purple polygon.

At the end of the unaligned blocks is a portal. Walk through it.

You will fall onto a small square area with a fence. Walk toward the upper part to activate a prompt to move a bridge.

Step back into the portal and make your way back through the unaligned blocks to the beginning. Go right this time.

Alternatively, you can fall off the blocks to return, but risk missing the green turf.

Head all the way right, crossing the bridge.

Once at the other side, stop and go down the ramp, then head left.

Straight ahead is another Dragon Eye.

Go back to the intersection and head straight, walking into the portal.

You will be back in the earlier part of the level. Cross the bridge, then go down.

Head all the way left, then go up where the two altars lie.

Place the Red Dragon Eye on Tsung's altar and the Purple Dragon Eye on Kang's altar.

Go to the portal and press X to exit this part of the level.

Jump off the cliff you are on to get the large medipak below.

Immediately head straight. In the next room, at the upper right, is a sniper cartridge.

Keep going straight to reach an intersection. The left path leads to the end of the level, while the paths ahead and to the right lead to power-ups.

To find power-ups, head forward from the intersection. There is nothing on the left path, so head for the right path. At the end of it is a large medipak.

Go back to the three-way intersection and head right. Go down when possible, as there is nothing if you keep going right.

Head right, then go up the first path. The second path offers nothing. At the end of this platform are some rockets.

Return to the main three-way intersection.

This time, go left, then head down. Go left until you reach a point where you can go down again.
