Chamber 4: Career Ladder

Push the stationary robot as far right as possible. This will drop the walking enemy robot to the lower floor. When the walking robot turns left, jump over the stationary robot, then jump up to the platform overhead and hang from it.

When the moving robot passes over the first floor switch, jump to the retracting platform. Immediately jump up through the platform above to access the next platform.

Push the second stationary robot down to the lower floor on the right. Then, push it as far left as possible so it stands on the floor switch. Wait for the walking robot to return towards the entrance. Jump up behind it to the platform you were previously hanging from.

Wait for the lowest platform to extend again. Immediately jump up through the second platform and stand on top of it. From here, jump up through the top level to reach the terminal. Before hacking, grab the hidden Helix if you need it; you won't have time after hacking.

Warning: All walls will close in rapidly after hacking the terminal. Immediately after hacking, jump right and run straight for the exit without delay.
