Tomb Raider: Underworld

All credits go to PlakaPlaka and radi500 for this video walkthrough. It is a walkthrough for PC, but the game is identical on Xbox 360.

At the beginning, you'll be in a small cave. Make your way through and you'll come to a large chamber. Here, you need to find two stone blocks to hold down a pressure pad that opens two doors. Make your way up the scaffolding on the right hand side and take the stairs down to the next area, where you'll find the two blocks. Bring them both back and place them on the pressure pad. Now, head through the side doors in the main area and solve the shadow plate puzzle by making an angel shape on each side of it. Everything else is quite linear. You'll make some more progress until you notice that the mansion is on fire. Then, you'll encounter Zip and Winston. Zip will shoot at you and then claim that someone looking like you set fire to the mansion. Then, you'll have to check the camera footage for evidence. Simply climb over the glass wall and check it. Then, Jacqueline Natla, the main antagonist of the game, will interrupt you and you'll make a narrow escape with your group. The achievement will unlock on the next loading screen.
