Dungeon Guide
The majority of ennemies of this mission consist of Glitch soldiers either using melee weapons (1-handed or 2-handed swords, or 1-handed sword + shield) or ranged (summoning some random monster with a capture pod and then switching to a bow). Glitch in FU are weak to Electric and Cosmic dammages and it would seem those Glitch soldier suffer the same weaknesses.

Entering the Tower
You will start the mission outside the tower. Head to your right and you will quickly meet with 2 melee Glitch. A bit further, you will a small tower holding the jail. 2 melee Glitch are patrolling inside and they will likely see you and exit the tower to attack you. Inside the jails, you will find 2 friendly Glitch that you can free. They will follow you and help you the same way crewmates would. You can also tell them to stay there if you don't want them to stick around you. You will then have 2 options: climb on the top of the jail or head staight for the Tower entrance.

Jail Roof
If you climb on the roof of the Jail, you will find some platforms to the right. You can use them to reach an area of the Tower that you cannot reach otherwise. As soon as you reach the Tower, a melee Glitch and a ranged Glitch will attack you. You will find stairs leading you down inside the Tower to the right, where another melee Glitch awaits you. The room to your left is guarder by a melee and a ranged Glitch. One stair below you, another melee and ranged Glitch are patrolling. On this floor you will find a console to the far right. Deactivating this console will disable the pitfall at the start of the Tower main entrance. Once the console is off, feel free to loot around and then head back to the Jail entrance. Head to the right from there to reach the main entrance of the Tower. With the console turned off, you will be able to cross the hallway behind the first wooden door without trouble. You will then reach a small garden were 2 melee Glitch will attack you. You will then reach a room with a door to the right a stairs leading below. The stairs are the way you come from if you didn't turn off the console.

Tower Entrance
If you want to head straight to the Tower main entrance, exit the Jail then head to the right. You will reach a wooden door leading in a small hallway. However this hallway is trapped and the floor will open up and you will fall in a pit. To escape this trap, interact with the wall to the left and you will open a way out. You will then reach a trapped room where you'll have to make your way down in the middle of fire traps. After crossing this room, you can see an opening on the wall to your left. You can go through there using your Sphere tech but you will have to cross a small lava pool while in Sphere, so if you don't have lava immunity don't try it. You will only find a merchant in the room on the other side, so you can skip it if you don't need to empty your pockets. You will then need to cross another trapped room: fire traps will periodically shoot from below you, just stop between them to not get hit. Then you will need to cross a puzzle jump room above a lava pool. Activate the switch to activate the moving platforms and make your way to the right of the room without falling in the lava (or just swim through the lava if you have lava immunity). The room to your right contains a pool of healing water. Exit the healing water room through the platforms leading you back up and head to your left. A melee Glitch will be patrolling inside the next room. Take the stairs to reach the room you reach at the end of the path if you go through the Jail Roof, or head to your left to enter a room guarded by 2 ranged Glitch. The next room is guarded by a Glitch jailor wielding a 2-handed axe or hammer (can't really tell which). You will find a few extra items in the room with the 2 ranged Glitch but that's pretty much it.

Inside the Tower
Both path will lead you in the same room. From there, head to the right and you will reach a room with stairs leading to the top right. 2 melee Glitch and 1 ranged one will ambush you in this room. After this room, you will reach another crossroad with doors leading to your left and to your right.

Left Path
The first room to your left is a puzzle jump room with some moving platforms above indestructibles spikes. This room can be pretty hard to cross using the platforms, so i would recommend using ropes, grappling hook or a way to fly to cross the room. A bow with a special of warp-point arrow can also be helpful if the player has enough energy to fully charge the shot. Midway through the room, 2 Batongs will appear to harass you. Open the metal gate and you will reach a hallway defended by 1 ranged and 1 melee Glitch. Head upstairs and you will reach a room guarded by 3 melee Glitch. You will find there 2 hostages Glitch and a Frog merchant to empty your bag. Exit the hostages room to the right and you will find another crossroad: the path to the right leads inside the library and the stairs lead to some dark looking room.

Library
The Library in heavily guarded: 4 ranged Glitch and 4 melee Glitch are patrolling inside and another ranged Glitch is waiting inside the samll room in the top right corner. If you add to that the monsters summoned by the ranged Glitch, you have quite a big fight on your hands. You can then exit the Library with the gate to the right. The path leading below open a way leading back near the puzzle jump room, so head upstairs instead, where you'll find the Dark Room to your left and a bridge to your right.

Dark room
If you follow the stairs, you will reach a vast empty room. However, once you reach the altar in the middle of the room, monsters will spawn inside. 3 Spookits and 3 Smoglins will appear behind you and 3 flying skeletal birds and 3 Apex Mutants will appear in front of you. The exit door to the right is not locked, so you can just ignore the monsters if you want. You will reach a bridge to your right.

Both path lead to the same bridge. Cross the bridge and you will reach a metal gate guarded by a ranged Glitch. The metal gate will lead you to a small room with a metal gate leading to the right and stairs leading you below. Those stairs are the way you come from if you chose the path leading to the right earlier.

Right Path
If you head to the right, you will find stairs leading upstairs to a locked door. The wall to the left of the locked door can be interacted with to open a small room with a lever, but it would seem this lever does absolutely nothing. Instead of taking the stairs, open the wooden door to the right. Keep going to the right and you will reach a pool of lava and an elevator leading below. If you have lava immunity, you can just cross the lava, but the elevator will allow you to cross it without lava immunity. Ride the elevator and watch out for the fire traps on your left and right on your way down. You can find a pool of healing water to your right with a small opening protected by spiked. This is a shortcut allowing you to skip a few rooms, but the only way i found to use it is to use the Sonic Sphere to pass exactly between the spikes. The "normal" path is to head to the left and ride the platform above the lava pool. Watch out for the fire trap along the way. You will then reach a room guarded by 2 melee Glitch. A console in the middle of this room will activate a hard light bridge above the lava pool above and open the door to your right. Head through that door and ride the elevators leading you back to the surface, right after the lava pool.

Then head through the metal gate to your right. Climb up the stairs that a melee Glitch patrol. You will then reach the Tower forge. The first room is guarded by 2 melee Glitch and 1 ranged Glitch and the second room is guarded by 1 melee and 2 ranged Glitch. Exit the Forge to the left and follow the path until you reach a room with a metal gate leading to your left (the way your come from if you took the Left Path earlier) and a metal gate leading to your right.

End of the Tower
Once you reached this room following either path, head to the right where you'll have to fight a lot of Glitch soldiers: 2 ranged and 4 melee Glitch will ambush you once you reach the middle of the room. Then head to the exit to your right and climb up the platforms. You will find a room with a checkpoint and a ranged Glitch. Once you're ready, cross the one way door to reach the Warlord Glitch, the boss of the Tower Invincible. Once you enter the boss room, a 25 seconds countdown starts. Once it reaches 0, a metal door will open on each side of the arena with a ranged Glitch inside. The door to the right is empty, i think that the ranged Glitch in the checkpoint room should be inside behind that gate instead.

The Warlord can be seen wielding a 2-handed sword before entering his arena, but i only saw him use his bow during the fight. He is a very healthy Glitch wielding a bow that shoot exploding fire arrow, but there's not much else to say about him. On his death, he will drop what you can expect to find in a chest: rng weapons, Manipulator Modules etc... Once the Warlord and his lackey are dead, exit the arena to the left and climb the stairs. You will then find the usual end of dungeon room, with a good ammount of chests, the diamond pedestal to turn in the quest and a teleporter to get back to your ship.

Secrets
The Tower Invincible hides a few secret rooms containing extra chests. You can find how to reach them here.
