The Ruins - Lone Labyrinth

Lone Labyrinth - Stage 1

Activate the orb and run across the new platforms to collect your items. Activate the next orb and have the gripshot hero go left, collect the bomb then throw it at the switch on the left. The same character should then head right to hit the next orb, while the fire gloves hero goes to light the torch. There is also a time limit as to how long the orbs and torch stay activated so be quick.

Lone Labyrinth - Stage 2

Light the torch and drop to carry everyone across the vanishing platforms onto solid ground. Light the torch there and continue onward with all your allies in tow. Step on the big switch here to summon some enemies that you must kill to move on. Go along the next section of vanishing pathways, where you'll have to defeat a group of colored Poes. The gateway opens afterward.

Lone Labyrinth - Stage 3

Hop down onto the vanishing platforms and carefully cross over to the torch to light it. Follow the next set of pathways until you reach the grate where you can throw a pair of characters over. Use the gripshot to get the last hero across as well. Next blow two people across the gap with the gust jar so the torch can be lit. Continue along the next path,killing colored Poes as you go to the end.

Lone Labyrinth - Stage 4

This boss level involves an encounter with a bunch of Redeads. Avoid getting too close so that you don't get stunned by them. Hit them with your items to stun them, and follow through with the sword. Repeat until all the enemies are gone, after which the gateway appears for you to proceed.
