Walkthrough[edit]

Climb up the stairs in front of you. There are a number of Firewalls blocking your way forward.

Turn to the right at the top of the stairs. You will find a number of Code Blocks and a Decoder Relay. Store all of them to make things easier.

Turn back to the middle of this first area with the opening in the ground. Use the Code Blocks to fill in most of the gap. Put 2 Blocks to boost the Decoder Relay to reach the target point on the Firewall.

Use the blocks to build out an arm to reach the target in the next firewall.

Lower the pillar and route the decoder beam into the target part of the wall.

With that wall destroyed, move the blocks out of the opening in the middle of the first area. This will let the beam reach the lower area, where you need to send it presently. Turn to the large area just opened up. There is a gap in front of you blocking the bugs. Drop down into that gap.

In this lower area, turn around and find the entry portal beam coming through. Jump across the gap and head over toward the beam.

Build out another arm with the Code Blocks and a Decoder Relay. Direct the beam down the hall away from the entry beam.

Once again, grab Code Blocks and use them to build another small area. Use another Decoder Relay to direct the beam into the channeling blocks to the right of the gap.

Head back up to the top level of the area now. Look in the direction you are sending the beam. Use Code Blocks to fill in the gaps that are blocking the bugs from moving forward. Fill in the second and third gaps much the same way.

With the path built, it is time to build your defenses for this memory. Build at least one Defense Construct on the far side of this, past the data stream. Be sure to build one on the other side of the data stream as well. Put one other in this area as well.
