Trashcalibur

 is a level in the Hobo Colony chapter.

Completing it unlocks Cleopatra.

Collect all five hidden scrolls
Reward: XP
 * In a small alcove in the first area you enter, to the right.
 * In the moonshine bottles near the barricade to the left, in the first area.
 * At the dead end to the right, after leaving the first area.
 * In the treasure chest #5.
 * Right next to the door leading to the end of the level.

Complete the level in five minutes or less
Reward: Mendel's Tasty Pea

Self-explanatory.

Find and open all the treasure chests
Reward: XP


 * Two inside the alcove on the right, behind a destructible barricade, in the first area.
 * One on the upper walkway. Can't miss it.
 * Down the walkway. Can't miss it.
 * Once you're going down from the walkway, instead of heading right, head down. The treasure chest is at the end of the lower path.
 * Once you hit the checkpoint and are attacked by Mulligan's men, the chest is down the right passage (away from the detonator).
 * The final chest counts.

Find and destroy the HoboBot
Reward: XP

Retrieve Trashcalibur in under seven minutes
Reward: XP

Self-explanatory. The time limit is actually fairly generous.

Do not get hit by any falling rocks
Reward: Leonidas' Tanning Oil

Tricky, especially in larger groups. Avoid the markers on your way and don't get into any fights with zombies needlessly. The brighter the target marker, the less time you have to get out of the target zone.
