Layer 5: Wrath challenges

 
5-1: In the wake of Poseidon
 
DO NOT TOUCH ANY WATER
 
 
First, drain the water. You must first drain the water by destroying three secret valves located in the first room of each level. After you have destroyed all three secret valves, a notification will appear that the water has been drained. You can now finish the level without touching any water. Be aware that not all water has disappeared from the level.
 
 

 
 

 
 

 
 

 
 
5-2: Waves from the starless sea
 
FIGHT THE FERRYMAN!
 
 
Simply throw a coin at the guy. That's it.
 
 
5-3: Ship for fools
 
DO NOT TOUCH ANY WATER
 
 
You will first need to place the skulls on their pedestals. This will open a secret passage. After carefully avoiding all the water, you can turn left to the flooded area. Instead of going straight ahead, take a right turn to the secret passage. This will take you to the end of this level, skipping the flooded one.
 
 

 
 
5-4: Leviathan
 
REACH THE SURFACE INSIDE 10 SECONDS
 
Pro tip: You can reach the surface using any means, not only the water elevator. The easiest way to reach the top is to ride a rocket vertically.
 
 
 

Layer 6: Heresy challenges

 
6-1: Cry for a weeper
 
BEAT THE SECRET ENCOUNTER
 
 
The red skull can be picked up before you head out to the outdoor area. The red pedestal is located on the top of the first building. The encounter will be activated by placing the skull down.
 
 

 
 
6-2: Aesthetics for hate
 
HIT GABRIEL INTO CEILING
 
 
Once he enters phase 2, stand underneath him and spam all of your weapons. The best nailguns with magnets or the Railcannon are the best.
