Portal 2: Team Building walkthrough

If your skill levels differ: Both bots carry the same kind of portal gun. Pings let you mark spots and time moves without talking, and failing costs little because a destroyed bot is rebuilt within seconds. How to split the roles

1. AtlasThe doors start opening once someone stands on the button in the centre of the room.
2. P-bodyShoot an orange portal into the wall panel beside the alcove button, then walk through the newly opened door.
3. AtlasStand on the second button, near the orange portal.
4. P-bodyTurn right, shoot a red portal into the panel there, so your partner can walk through and join you.

1. BothOne bot puts a portal on the panel on its side of the goo, steps through and waits by the door.
2. BothHitting the pedestal button opens the door for the other player.
3. AtlasGo through the door and shoot a purple portal into the corridor panel; your partner then comes through the blue portal.
4. BothEach portal up to a high pedestal button, count down, press both at once, then drop and press the lower button on your side.
5. BothGrab the ball that drops out and set it in the receptacle; that unlocks the exit.

1. AtlasPlace the pivot cube in the laser so it aims at the alcove side, then portal the panel it hits and a side wall to route the beam through the relay.
2. P-bodyStanding on the button shows the turrets hidden behind the glass.
3. AtlasPoint the laser through the glass to kill the turrets, then turn it onto the left one of the two panels sitting next to each other.
4. P-bodyWalk into the glass corridor, shoot a portal at the wall panel on your right, then shoot the other at the panel across and stand under the receiver.
5. AtlasFill both neighbouring panels with portals so the relay and the receiver switch on the stairs up to the dual door.

1. AtlasBlue portal on the panel close by, purple into the start of the maze, then go through blue and keep going until something blocks you.
2. P-bodyAlternate between the down and up buttons so your partner can move through the maze blocks.
3. AtlasBring the pivot cube back through the purple portal and place it so it redirects the laser beam into the adjacent panel.

1. AtlasPlace the pivot cube in the beam aimed at the left receiver to raise the left crusher.
2. P-bodyWalk under the raised crusher onto the goo platform, then portal to the lift rising from the goo near the other crusher.
3. AtlasLet the lift rise above the crusher, then aim the beam at the right receiver to raise the right crusher.
4. P-bodyJump under the crusher once it is high enough, then continue to the exit.
5. AtlasSend the beam back to the left receiver, drop the cube, then pass under the crusher and take the portal over to your partner.

1. AtlasUse the panel on the catwalk to portal across the gap into the office area.
2. P-bodyFollow your partner to the two switches.
3. BothUse the ping tool's countdown so both switches are pulled at the same time.
4. AtlasGet a portal through the door before it shuts and the other on the wall, step through and look for the disc.
5. AtlasBring the disc to the player and slot it in; that ends the course.
