Welcome to Fatal Experiment 2 Randomizer Edition by Project Zaero.

Please report any issues you find to Project Zaero#9999 on Discord.

The "Deep End" of GTFO Modding, but randomized.

  • Enemies spawning in levels and from Blood Doors are random! Survival Waves (alarms, events, objectives) are not random due to how those system work.

  • "Version Swap" to pick different randomizer modes. These require manual replacements.

    • Versions include: "Fair," "True Random," and "Bosses Only."
    • Fair = Enemies swapped out based on their "tier." This is the default mode. This prevents Strikers from being swapped for Charging Mothers.
    • True Random = Indiscriminate enemy swapping. You'll probably die.
    • Bosses Only = I don't recommend this one but you know you want to try it anyway.
    • Redemption and Eclipse options available as well, to swap enemies with ones from those rundowns. There's also an option for having enemies from all 3 rundowns!
  • "Gear / Mobility Swap" to pick different loadout restrictions. You can choose whether you want to use the original Fatal 2 weapons, Redemption weapons, or Eclipse weapons. You can also choose if you get Infinite Ammo or Eclipse-style mobility!

  • 15 Classes to pick from that evolve over the course of an expedition by earning XP from kills and assisted kills. The Solo category is unrestricted in this version of the mod. Playing a Moblity Swap that includes Eclipse movement will cause every class to have Double Jump unlocked at LV0.

  • Many enemy variants with different abilities such as grappling, bleeding, knockback melee, and more, many with custom models and graphics.


  1. Open r2modman Settings -> Browse Profile Folder- > BepInEx\plugins\ProjectZaero-Fatal_Experiment_2
  2. Open "Swap Enemies" or "Swap Gear" folders.
  3. Open your desired version. Copy everything inside. This will include a "Custom" folder and a bunch of "GameData" files.
  4. Go back to BepInEx\plugins\ProjectZaero-Fatal_Experiment_2, then go into Fatal Experiment 2.
  5. Paste your copied files. This will overwrite them with your new settings.
  6. Reboot the game and enjoy!

Note: To reset to the original / default Randomizer settings, either reinstall Fatal Experiment 2 Randomizer Edition, or copy+paste "FXP2 Fair - Default" from Swap Enemies and "FXP2 - Default Gear and Movement" into "Fatal Experiment 2."

Make sure each player has the same settings or you will be kicked from the lobby!
