Recompile (EU)

Pretty much the same solution as for completing the TET Biome, with memories highlighted in bold

First Stage:
After you get teleported turn around and head up to the facility. Once inside the complex look right, there's a save point and a triangle node go get that first. Head back to the main path, there will be a button on the floor, don't press it just yet, instead jump on some rocks to the right of it and head for the second triangle dialogue node. Get back to the button and press it, there's a robot sitting on the next button just shoot it to wake it up and destroy it. Press both buttons and cross the newly created bridge. Another button here you need to press (it spawns a flying robot). Climb the green stairs up to press the second button, this will spawn another flying robot and disables the spawner. After you pressed the button and dealt with the robot look a bit to the right, there's a third triangle dialogue node we need to get, jump on the first platform and go down following the path to the node. Once there keep heading straight across the pentagons, again 2 buttons here you need to press to disable to green shield I pressed the top one, bottom one top one and spheres just kept spawning so I pressed the bottom one again lol, anyways the shield is now disabled and you can proceed, just past where the shield was there's a save point to the right, get it and keep heading straight across the pentagons. Don't press any buttons here instead go left across some tricky platforming to collect your 4th triangle dialogue node. Just past that there's an ability upgrade (second hacking upgrade). Get back to the buttons puzzle, there are 3 switches here, 2 close by and a third one at the back to the right. I hit the one at the back first and then the very first one and it seemed to do the trick, new enemy spawns here, flamethrower guy, use your time slow down to get rid of him before he gets too close, use the elevator to go up and collect your second delete ability, head through the portal.

Second Stage:
The second area is way bigger, at the start just head towards the facility and climb up, once you get there a dialogue will start. There's a dialogue node close by, to the left, climb the wall and you should see it. Next go back and head all the way right, you should see yet another triangle node dialogue in the distance, little tricky to get, climb the little ledge and jump up, it's possible, if you can't get it delay your jump by a bit. Go back to where you first entered the facility and go down the stairs to get the save point. If you look left there's another triangle node in the distance on a platform. Get it and drop down, press the button and you can get your second upgrade ability, just to the right of the button. Step on the button again and use your new dash ability to dash past the opened security wall, it's on a timer so be quick, if you can't make it hit the button again and try again. Once you make it past you'll drop down and there will be a button just in front of you, don't hit it just yet, look right and up, there's another dialogue node. Hit the button and it will take you back to the place where you first climbed the building so just climb it again and get back to the save point. Now, keep heading straight past all the switches all the way to the back of the room for another dialogue node. Now start hitting the switches, dash to the one past the dialogue node and head back to the save point, there should be 2 switches on the way (one next to the elevator and one next to a bright shining triangle). One is to the right of the save point in a small alcove and the remaining one is to the left. Keep heading to where you got your dash ability but instead of going left to take the platforms down go right of the wall. It will take you to a new place, hit the switch and enemies will infinitely spawn till you hit the second switch, there's also third weapon upgrade here, farm kills with the shotgun here, after you hit the second switch head back to the save point and hit the last switch just by the save point, take the elevator and cross. as you cross the bridge there will be a triangle dialogue node. After you crossed the bridge take the way left and keep following the way up until you get to the very top, there's a dialogue node here you need to get, pretty tricky. Head to the left n back of the room there's a wall you can climb to get over the glitched are, see screenshot below.



After you've collected your dialogue node head back to the top of the tower a hit a switch. This will unlock next area, head there. There are 4 switches in this area, you need to hit all of them to progress (first the one on the left then the one on the right) repeat for the next row of switches. 5 enemies will spawn and you need to kill those to progress. With the shield around the area down you can now get to the 3rd stage.

Third Stage: (BOSS)
No Memories here

Fourth Stage: (FRIENDLY)
Easy stage, keep heading forward, do not shoot enemies as they are friendly (might or might not aggro), after you cross the bridge take your 4th weapon ability right in front of you. There are last 2 additional dialogue nodes one on each side, it should be pretty obvious. The exit is just ahead, exit to get your achievement.
