📋 About This Mod
Adds a powerful jetpack that allows you to zip through the caves. Try not to hit your head.
CU Turbo Jetpack
A scratch-built twin-tank thruster worn on your back, with a real flight model and a fuel tank that only refills with your feet on the ground.
Features
-
[]Adds the Salvager Turbo-Jetpack (turbojetpack), worn in the back slot.[/]
[]Double-tap jump and hold to burn; release to cut the engine.[/]
[]The tank holds about 6 seconds of continuous thrust, and only re-pressurizes while you are standing on solid ground, what you take into the air is all the air time you get.[/]
[]A floating fuel gauge appears over your head: green to amber to red, flashing on fumes.[/]
[]Low tank makes the burn pulse and stutter. A wet engine misfires. A worn engine coughs.[/]
[]A small tool pouch riveted between the tanks softens the loss of your backpack slot.[/]
Which file do I download?
-
[]All-in-one (with BepInEx) - the mod plus the loader that runs it. Pick this if you have never modded this game before. Nothing else needed.[/]
[]Plugin only - just the mod. Pick this if you already run other mods for this game, or you use a mod manager.[/]
Installation
All-in-one: extract everything into the folder containing CasualtiesUnknown.exe, say yes to merging, and launch the game. That is the whole process.
Plugin only: extract into that same folder so the mod lands at BepInEx\plugins\CUJetpack.dll, then launch.
Installing the all-in-one over an existing BepInEx setup is safe - it only puts the same loader files back, and does not touch your configs or your other mods.
Mod managers: install either archive as-is. Both are laid out from the game root.
Requirements
-
[]Casualties Unknown (demo build - Unity 2022. 3, Mono x64)[/]
[]BepInEx 5 (x64) - included in the all-in-one download. Only needed separately if you take the plugin-only file.[/]
Compatibility
Safe alongside the other Casualties Unknown mods on my profile.
Not working?
-
[]No BepInEx\LogOutput.log after launching the game means the loader never started. winhttp.dll has to sit directly next to CasualtiesUnknown.exe - if you extracted into a subfolder, move the files up one level.[/]
[]Some antivirus tools quarantine winhttp.dll, since hooking the game is exactly what it does. Restore it and add an exclusion.[/]
[]Steam users: right-click the game, Properties, Installed Files, Browse, to find the real game folder.[/]
[]If the log exists but the mod is missing from it, check the file really is at BepInEx\plugins\CUJetpack.dll and not nested one folder too deep.[/]
Uninstall
Delete BepInEx\plugins\CUJetpack.dll. No game files are modified, so nothing else needs undoing.
Notes
Everything is patched in memory at load through Harmony - your game install is left untouched.
Credits
The mod itself is my own work.
The all-in-one download also contains the BepInEx mod loader, bundled unmodified so that people without a mod loader can install in one step. It is not my work:
-
[]BepInEx 5. 4. 23. 2 by the BepInEx contributors, licensed under the LGPL-2. 1 - github.com/BepInEx/BepInEx (license)[/]
[]BepInEx ships with, and this bundle therefore also includes, UnityDoorstop 4. 3. 0 and HarmonyX 2. 9. 0, under their own respective licenses.[/]
The plugin-only download contains no third-party files - it is just my compiled mod.
Plugin ID: casualtiesunknown.cujetpack - version 1. 0. 0
