- No Sanity Loss — Sanity / fear meter pinned at max.
- Infinite Stamina — Sprint from stalkers without gauge drain.

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 Letter Lost 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
- Apply the trainer only on the Steam build. Pirated, cracked or region-specific copies often have shifted memory offsets and the cheats silently fail.
- Quick-save in Letter Lost just before toggling any XP or economy cheat — that way a rogue multiplier never snowballs your progression.
- Pair One-Hit Kill with Stealth Mode in open-world maps to clear camps without spawning reinforcements.
- Keep Mega Damage disabled during boss phase transitions — skipping a phase can leave the fight unkillable.
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 FlatNine Games update.
Compatibility & Safety
The trainer is built for the single-player mode of Letter Lost. Avoid using it in online or competitive matches — anti-cheat frameworks like EAC, BattlEye or VAC can flag memory manipulation and suspend your account.
Frequently Asked Questions
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.
Will this trainer trigger my antivirus?
Some antivirus programs flag trainers as false positives because they modify running-game memory. Temporarily disable real-time protection or whitelist the folder before launching.
Is the Letter Lost trainer free to download?
Yes — this build is 100% free. No paid unlocks, no forced registration, no hidden fees on FLiNG Trainer.
Which game version does this build support?
The release targets the latest Steam edition of Letter Lost. Earlier versions may work but are not officially supported.
Does it work in online or multiplayer mode?
No. Use this build only in offline or single-player mode. Online anti-cheat systems (EAC, BattlEye, VAC) can ban your account.

Safe to Use — 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.
Verify the file yourself: Upload it to VirusTotal.com to scan with 70+ antivirus engines before running.
How to Install the Letter Lost Trainer
- Download the trainer archive from this page (button above).
- Extract with WinRAR or 7-Zip — password if any is shown beside the download.
- Disable real-time antivirus only if a false positive blocks extraction. Trainers modify game memory; many AVs flag this as a generic heuristic. The included VirusTotal scan is your sanity check.
- Launch the game first, reach the main menu, then start the trainer as Administrator.
- Use the listed function keys (F1–F12) to toggle each cheat — health, stamina, money, ammo, instant skill cooldown and so on.
Compatibility & Anti-Cheat
Letter Lost trainer targets the single-player and offline modes on the exact game build noted at the top of this page. It is not designed for online or multiplayer play and should never be used with Easy Anti-Cheat, BattlEye, FairFight, or VAC-protected lobbies — running a trainer there can result in a permanent ban from the game's matchmaking servers.
Troubleshooting
If the trainer hotkeys don't activate: confirm the game version above matches your installed copy (Steam → game properties → Updates), install the latest Visual C++ Redistributables, and verify your antivirus hasn't quarantined the executable. After a game update, check this page for an updated trainer build before reporting a problem.
