The decoder beam will be coming from above. First, collect the code blocks and decoder relay from the alcove to the right. Now create a decoder stack and guide the beam to destroy the smaller firewall covering the alcove across the other one.

Once it’s cleared, store all the blocks from the alcove. The weak point of the large firewall near the starting spot is located on its side, in the corner. Remove one code block from your decoder beam stack. This will make the stack of the first decoder relay about two blocks high. Now create another stack so that you can place another decoder relay that will lead the redirected beam to the weak point.

When the firewall is down, disassemble your decoder stacks and store all blocks, then go down the lower platform. The beam from above should pass through from the opening in the upper platform. Now create a short ledge in the middle with two blocks and a decoder relay pointing towards you.

Next, place a code block on the gap in front of the wall relay to the right then place the second relay on top of it to power up the extension platform. This will destroy the last firewall protecting the memory data stream.

Before completing the bridge for your indexers to cross, make sure to place your defense turrets along the way, preferably covering the whole stretch of the bridge and one near the data stream itself. Once done, complete the bridge and wait until your indexers completely bring back the necessary data bits to your base.
