Successfully complete the indicated task to unlock the corresponding area of the Krypt. The Krypt is Shang Tsung's island that can be explored from a third-person perspective. The island contains many puzzles and locked doors. The Krypt allow you to unlock new fatalities and brutalities, alternate costumes, character art, and more. Note: Not all key items can be found in the Krypt. Some of the key items are randomized, and rewarded for completing challenges or unlocking containers.

Shao Kahn's Hammer: The hammer is located near the start of the Krypt. It gives access to most of the above-ground areas of the island.

Motaro's Horn: Go to the Warrior Shrine, and break the meteorite (that lands in a cutscene) to collect the Gem Of The Living. Return to the Courtyard and smash through to the gong-room on the east side. There is a locked door that requires the Gem Of The Living. Return to the Vault through this door and use the switch to find Motaro's Horn. Use it to unlock the Underground area.

Ermac's Soul Amulet: In Goro's Lair, search the southwest corner for a hall leading to a circular room. Take the elevator down to reach the Lower Pit. Ermac will drop into the spikes. Grab his Soul Amulet to unlock the power to control souls. With the amulet, you can then unlock the glowing-green Krypt objects. You can also reach new areas by spending souls. Use the Soul Amulet to fix the bridge at the Pit for 1,000 souls.

Spear Of Hanzo Hasashi: This item can be found in The Armory, through the hallway behind Goro's corpse in Goro's Throne Room. You can throw the spear at unreachable objects to unlock new paths. For example, use the spear to break the lanterns at the Wooden Bridge. You can also use the spear to pull hanging corpses. You will rip them in half and collect the heart inside.

Kenshi's Blindfold: This special blindfold gives you sight into the realm of spirits, making once invisible locations/items visible. To find the blindfold, travel to the Jails through the right-most hallway in Goro's Throne Room. Use the blindfold in previous areas, and to reveal new weak walls.

Remaining items: Many of the other items required to progress in the Krypt are earned randomly. These items appear when opening chests/containers in the Krypt, or as rewards for completing Tower Of Time challenges.
