Tomb Raider: Underworld - [Arctic Sea] – Out of Time - part 2 - game guide, walkthrough, secrets, game tips & strategies

When you move to the top, the Natla will attack you again. Evade the fireball and enter the platform.

Push another block on its place. This will activate another seal.

Run right and evade Natla’s fireballs and Yetis. Stop in front of a vertical fragment of the wall with metal roundel.

Fire the line and pull yourself up. Start swinging and jumping to the edge on the right side. After that climb on the top of the platform.

Next, jump down to the nearest levitating block and wait for the moment when it will transport you to the place where thanks to a long jump you will be able to clutch another edge.

Destroy the seal. The next part of the device will be destroyed.

When you do this another Yetis will walk out of the corridor. You can ignore it. Jump on the block…

From it jump on another which is closer to the center of the room. After that jump in the direction of the tower and clutch one of the ledges.

Start climbing up. In a certain moment, the time will slow down again and Natla will launch another fireball. Jump in the direction of the ledge which is located above you.

Wait for the moment when the dome will turn. You will find yourself near the last working device which is supporting the construction. Release the edge and slide down on the platform.

Destroy the last seal and watch the outro.
