Chamber 9: Block The System

First off, you need to drop the Block. Once it's down, hit that button to get it moving. This will activate two laser beams around you. Crouch-walk to keep pace with the Block and just wait until those lasers shut off before you move forward.

Next, hack that panel. When the Block starts to move upwards, you'll want to watch the shadow it's casting. Wait until the shadow covers the ledges you need to jump onto. Once you're up there, activate the panel. Then, hop onto the Block immediately and ride it all the way to the top.

Jump over the platform and then hop over to the terminal you need to operate. Now, if you're hunting for that hidden [Helix], make sure you follow our special box-out instructions *before* you approach the Block and it starts moving away from you. If you're not going for the Helix, drop down into the shadow cast by the moving Block. As soon as the left side of the shadow covers the middle terminal, quickly hack it – you'll have just enough time before the shadow moves off. Dash to the next panel and activate it just as fast, because you've got a tight window in the shadow. You'll need to do this one more time with the third panel.

Finally, run left and jump into the cubby hole. Push the Block to the right so it drops into the hole. Then, push it through the teleporter. Drop down behind it and give it another little push to the right. This will give you easier access to the exit up above.
