sp_a2_turret_intro.bsp Turret Intro

This is the twenty-second level of the game, and is set within a dilapidated Test Chamber. This level reintroduces the player to Turrets, and the way in which they can be disabled through direct interaction, or by using a Weighted Storage Cube.

Walkthrough

Pick up the Turret in front of you and throw it sideways to disable it.
Look around the corner and fire a portal on the wall behind the second turret. Then place the other portal on the wall next to you.
Lift the turret through the portal and disable it by putting it sideways on the floor.
Go to the corner where the turret was and go to the right.
Place a portal under the third turret and it will fall through and be disabled.
Go where the third turret used to be and then go up the stairs.
Shoot a portal above the nearest turret and the other one under the Weighted Storage Cube on the floor in front of you.
Do the same to the other turret.
Pick up the last Storage Cube and carry it to the other side of the glass.
Go around the corner and use the Storage Cube as a shield when knocking over the remaining three turrets from closest to the furthest.
- This section can also be passed by placing portals above the final three turrets, and a portal on a wall in safety, and dropping cubes on the turrets.
When all of the turrets are disabled, place the Storage Cube on the button.
Go in the Chamberlock and jump down from the catwalk.
Walk to the catwalk on the left and through the door.
