Deep Desert Testing Station Guide - The Forgotten Cells

Deep Desert Testing Station Guide - The Forgotten Cells

Written by MJM - 9th July 2025

The 'Forgotten Cells' Testing Station is a 'challenge mode' Testing Station which can only be found in the PVP section of the Deep Desert. This is one of the longest and hardest Testing Stations so be prepared for a bit of a slog.

Warning: This Testing Station is designed for small groups, but can be done solo. However you will be locked in to multiple rooms where you will encounter many waves of enemies. We recommend a Mk6 Weapon, Power Pack & Shield.

  • Length: ~40 minutes
  • Challenge: 3 Lock-ins, ~9 Waves
  • Solo Difficulty: Hard

The Forgotten Cells Testing Station - Map & Route

The Forgotten Cells features three separate 'lock-in' rooms but is otherwise a fairly linear and easy to follow layout.

Combat Section - First Lock-in

As with all Testing Stations, head on down the stairs and through the first room. Take the corridor on the right and follow it until you reach the first green shield door. Once you enter through this shield door, you will be locked in to the first combat room.

The first 'lock-in' room is the easiest. You'll be in a large room with a staircase that runs around the perimeter. Make good use of the side room to pull the melee enemies away from the ranged + heavy enemies.

Keep moving, don't get pinned down and you'll breeze through this first room.

Combat Section - Second Lock-in

Once you have cleared the first room, head on up the stairs and through the now unlocked shield door to enter the next lock-in room. This one is a little harder than the first but still not too bad as you can use both floors.

There isn't a side room or any other great location you can use as a safe zone but just hide behind the large containers or any other object to break the line of sight of the ranged enemies while you deal with the melee enemies.

Clear this room to head on into the final, and most challenging, room.

Combat Section - Third Lock-in

Enter through the shield door to enter the final room, which is littered with glass-walled prison cells. This room is pretty tough and you'll have to deal with multiple waves of many enemies, it's much tougher than the other rooms, especially once the flamethrower heavies start pouring in!

Use the cells on the ground floor as these provide great cover to allow you to break line of sight. Use them to bring all of the melee enemies to you.

Make use of the upstairs section of this room as well when the enemies start to group up, you can run up and then jump off back to ground level to break up the enemies and make it easier to pick them off.

Reward Room & ID Band

You made it to the end! Congratulations. Head on through the unlocked shield door and follow the corridor around until you see both the Reward Chest and Purple ID Band.

Usually the loot in this Testing Station is pretty epic, so enjoyed your well earned schematics.
