Hideout: The Evil Shrine

The hideout has several similar or repeating trap rooms. In this area you can find an ordinary chest and the computer room. However, there's also an easily missable doorway leading to another area.

The second area has several enemies and destructible objects, yielding additional blocks. In the end, there's a superhero chest you can loot. If the computer room is in the previous area, you have to backtrack all the way there to access it.
