First, remove the middle block on the top layer to let the decode beam break down the first firewall. Once done, store all the remaining blocks for later use.

The second firewall to the immediate left requires another decoder relay. It’s found on the alcove above the second firewall. Create a foothold so you can jump and reach the alcove and collect the blocks there. Like before, store the code blocks for later use.

Now stack up to code blocks on the spot in front of the firewall’s weakpoint and the decoder beam’s path. On the third layer, place a decoder relay and bend the beam towards the weakpoint.

Once the firewall’s gone, store all the blocks in your inventory from the lower alcove then reposition your decoder relay stack so it hits the wall relay and powers up the extension relay above. This will remove the large, third firewall.

Next, climb the layers of fixed code blocks and you’ll find the last firewall’s weak point above. You need to create another code relay stack so make sure to position it in front of the firewall’s weak point and divert the decoder beam there. Finally, lay down the defenses and complete the path for your indexers to cross.
