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

The "Deep End" of GTFO Modding.

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.

34 Custom Guns (8 are level specific).
Custom Sword Melee Weapons. (Huge anime sword currently disabled)
Heavily Modified Vanilla Melee Weapons.
Flashlight tool for Steatlh expeditions.
Terrible Custom Vanity Helmets.
Terrible Custom Palettes.
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

V2.2.0

Fixed issues with R7 infection resistance change.
Act 2-1 "Restore" and Act 5-1 "Chaos" fixed and reenabled.
Charged Revolver reload speed slightly nerfed and fire rate increased to make it harder to use.
Updated terminal localization for R7 Hotfix 1.

Known issues:

V2.1.1

Hunter and Assassin now receive their max melee damage at LV1 instead of LV5, dramatically improving their early and mid game. Their max speed is also increased from 112.5% -> 120%. Their reward for leveling up is armor and speed.
Outlander now becomes infect immune at LV1 instead of LV13, and their melee armor has been doubled from 115% -> 130% at LV15.

V2.1.0

Missing localization for terminals. Should not impact gameplay for the most part. Will be fixed soon.

V2.0.2

V2.0.1

V2.0.0

Updated for Rundown 7 Compatibility
Most of the dependencies are currently removed until they are updated to R7. This includes GTFuckingXP, DoubleJump, and ResourceHelper. Strongly advised to make a new profile for this build.
Bio-Tracker enemy names simplified and have larger text. i.e., "Giant Striker" will now simply be "Giant" with a red tag, "Giant Shooter" will now simply be "Giant" with a pink tag. This reinforces learning the color codes while making the information easier to read. Still can be disabled in config settings.
