Frequently Asked Questions
Which game version does this build support?
The release targets the latest Steam edition of Boss Key. Earlier versions may work but are not officially supported.
Can I request a new feature?
Yes — send a request via the comment section. Requests with a specific save file or reproduction steps are prioritized.
Is there a Windows 11 build?
Yes — tested on Windows 10 and Windows 11 (x64). Older Windows 7/8 builds are not maintained.
How do I activate it?
Launch the game first, then run the trainer as administrator. Use the listed hotkeys (F1, F2, etc.) in-game to toggle each option.
Is the Boss Key trainer free to download?
Yes — this build is 100% free. No paid unlocks, no forced registration, no hidden fees on FLiNG Trainer.
This robust Boss Key trainer ships with 13 fully working options tailored for the survival genre. Each one is memory-driven and toggled from a hotkey, so you never leave the game window:
- Instant Harvest — Crops mature on plant.
- No Tool Durability Loss — Axes, picks, weapons never break.
- No Base Raid Timer — Hostile raid timers paused.
- Unlimited Ammo / Arrows — Ranged stacks never deplete.
- Freeze Enemy Spawn — Night hordes stop spawning.
- Freeze Weather — Stops storms and blizzards mid-session.
- Breed Timer Skip — Baby animal timers zeroed.
- Unlimited Fertilizer / Water — Farm plots always watered.
- Tame Animals Instantly — Taming bar fills to 100% on click.
- No Fall Damage — Cliff drops deal zero damage.
- Unlimited XP — Level bar refills per action.
- Unlimited Torches / Fuel — Light sources never burn out.
- Max Crafting Skill — All skill trees at max.
Screenshots
How to Install
- Download the archive from the link below.
- Right-click the archive and extract it with 7-Zip or WinRAR (password: flingtrainer).
- Temporarily disable your antivirus or whitelist the extracted folder.
- Launch Boss Key and load any save.
- Alt-Tab out of the game, right-click the trainer executable and choose “Run as administrator”.
- Back in-game, press the listed hotkeys (usually F1, F2, F3…) to toggle each option.
- Avoid alt-tabbing repeatedly while cheats are active — some toggles reset on window switch.
Pro Tips from the Editor
- If Windows Defender deletes the exe on download, add the folder to exclusions before extracting the archive.
- Run the trainer after loading into a save, not from the main menu. Some games replay the intro with modified memory and glitch.
- If an option does nothing, the game just patched. Close the tool, wait for an updated build and re-test — old pointers stop firing after hotfixes.
- Quick-save in Boss Key just before toggling any XP or economy cheat — that way a rogue multiplier never snowballs your progression.
How This Trainer Compares
Compared to generic cheat engines, this release ships with pre-built, version-locked hotkeys — no manual pointer hunting, no CE-script imports, no waiting for community tables to catch up. The downside is less flexibility: you cannot add custom options, but the upside is near-zero setup friction and a faster patch cycle after every Institute of Card Game Studies update.
Known Limitations
- Online and co-op modes are not supported. Use the trainer offline only.
- Some options (mega damage, one-hit kill) may interfere with scripted boss encounters — disable before cutscenes.
- Antivirus false positives are common; the trainer injects into process memory, not system files.

Antivirus False Positive Notice
This trainer uses memory-editing technology to modify game values in real time. Some antivirus programs may flag it as suspicious — this is a known false positive common to all memory-editing software, not an indication of malware.
