In this puzzle stage, the decoder beam will be coming from the far side of your starting point. The beam is blocked by a code block in the lower platform near your base. Get to that platform and store the block to let the beam power up the extension platform, which will produce another decoder beam in the main platform.
Get back to the main platform and remove the code block that’s blocking the beam. Once it’s able to pass through, pick up the decoder relay from the pile of blocks in the corner then place it on top of the stack of two blocks. Rotate the relay so it bends the beam towards the right. Remove the block to let the beam pass through.
Go through the tunnel and you’ll find another decoder relay right outside the tunnel and the massive firewall in front of it. Create a stack of two code blocks with the decoder relay on top so that the beam bends and hits the firewall’s weak spot.
Before creating a bridge for your indexers, make sure to place at least two defense turrets along the path from the tunnel to the data stream and one near the tunnel entrance. Place the other two turrets along the open space leading back to the base.
