Hidden Roll Attack Skill:
Sundered has a hidden skill, the roll attack, you can find in the first
area below the main hub. To the right of where you acquire the cannon
skill is an area that requires two end game skills to access, the hook
and the wall run. In this skill gated area are endless waves of very
strong enemies, and in the top right corner of the zone is an unmarked
room with a corrupted treasure chest. Attack the chest enough to get
the roll attack skill!

All Endings:
There are 3 endings in Sundered, and each ending features a unique final boss.
Depending on your choices in-game, you’ll experience one of theses final

-=Beacon of Hope=-
The Beacon of Hope ending is acquired if you destroy seven Elder Shards.
To destroy Elder Shards, find the Furnace chamber in Area #2.
Check your map for a fire-like icon.

If you use any Elder Shards to corrupt abilities, this ending will be
locked out.

The final boss for this ending is The Shining Trapezohedron.

-=One With The Void=-
This is the easiest ending to acquire. All you have to do is use all seven
Elder Shards to corrupt seven different abilities. You can corrupt abilities
from the Shining Trapezohedron shrine where you respawn after death.
The final boss for this ending is Humanity.

The most common ending and the one most players are probably going to acquire
in a normal playthrough. For this ending, don’t destroy or corrupt all seven
Elder Shards. If you stay in the center of the sanity alignment system, you’ll
face off against this evil creature without forsaking humanity or completely
turning against the Shining Trapezohedron.

The final boss for this ending is Nyarlathotep, naturally.
