The Great Pyramid - From the Level Start to the Secret

After the level transition, continue along the twisting tunnel from the MASTABAS and climb out into another ruined tomb (blue #1 on the Mastabas map).

Pick up a small medipack and shotgun shells in the northeast and southwest corners. Use your pistols to shoot the boards blocking the doorway.

Then, if you like, switch to more powerful weapons to kill the blue-robed mercenary waiting just outside on the right.

Across the excavation pit to the left (west) is another mercenary. You can probably kill him from here with the pistols. Lara won't aim at this distance, but if you stand near the edge of the pit and face him squarely while shooting, it should still work. You'll see blood if your shots are connecting.

When he's dead, take a running jump across the pit to the left (south) side. Run into the doorway on the right for cover because another enemy now starts shooting from across the pit (on the north side).

Again, you may be able to hit him from a distance with pistols, but if he starts shooting back, you can switch to the crossbow or revolver.

Kick down the door of this building (#2 on the map). In addition to the mercenary waiting inside, there's also a giant beetle. If you run inside and fire immediately, one grenade or explosive arrow should kill both.

After you clear the room, find the concealed trapdoor in the floor. Lighting a flare can help you spot it. It's the one square that's divided into smaller squares. Position Lara facing west, standing just outside the edge of the trapdoor. Press Action to lift the trapdoor.

Climb down the ladder to the bottom of the shaft.

Here you'll find the level's only SECRET (68/70), the GRENADE GUN (or 10 grenades if you already have the weapon). Climb back up the ladder.
