The "Deep End" of GTFO Modding.

• 10 Campaign Expeditions: Experience the storyline in Fatal Experiment 2.
  • Expeditions may last over an hour and will challenge your team.
• 15 Bonus Expeditions: Arcadey / challenge levels.
  • Typically 10 to 40 minutes, these levels are to-the-point and get you straight into the action. They vary drastically and offer a wide variety of experiences.
• 44 Custom Guns (6 are level specific).
  • Recommended to not use WeaponStatShower as it will hide information about custom weapon behavior.
• Custom Melee Weapons: Sword, Sleeper Buster, Stick.
  • Heavily Modified Vanilla Melee Weapons.
• Flashlight tool.
• 15 Classes to pick from that evolve over the course of an expedition by earning XP from kills and assisted kills.
• Many enemy variants with different abilities such as grappling, bleeding, knockback melee, and more, many with custom models and graphics. Because there are so many, here is a ridiculous spreadsheet with more info: https://docs.google.com/spreadsheets/d/1FbHNg9RaJdX1NFwiVOPX25fchjfBawKsx4SGjcdoG5c/edit?usp=sharing

V4.2.0

Gear Balance Overhaul TLDR:

  • Recommend not using WeaponStatShower since it hides this info. Added more info to text to compensate.
• Tightened the gap between primaries and specials.

  • Avg. Damage Efficiency: 800 -> 1800
  • Avg. Damage increased by ~80%
• Specials
  • Avg. Damage Efficiency: 3000 -> 2200
  • Avg. Damage reduced by ~20%
  • Reduced crit multipliers by ~50%
• Adjusted reload cancels to be more visually accurate and adjusted reload times to compensate.
  • Most affected reload cancels are less effective, with a couple improving.

New Primary

• Soul Nuker
  • Primary complement to the Soul Sniper. Fires an explosive shell, dealing immense damage over a huge area.

Miscellaneous

• Updated Afflicted textures

• Increased amber flashlight range: 8m -> 10m
• Machine Stick damage increased by 50% to match the intended DPS (hit rate was lower than expected)
• Adjusted knife hitbox to the "fixed" version

Gear Balance Changes
