Kumitantei: Old-School Slaughter Trainer

Invisible to Stalkers turns Kumitantei: Old-School Slaughter into a walking simulator with horror aesthetics — perfect for a second playthrough where you want to explore every room and read every note without being chased. Flashlight batteries are the real final boss in horror games. Infinite Flashlight Battery means you never have to fumble in the dark during the most intense sequences. Speed-running horror games requires frame-perfect movement. Super Speed and Noclip give you the routing tools to find optimal paths through every chapter.

You Asked — We Answered

Is there Windows 11 support?

Yes — tested on Windows 10 and 11 (x64).

Who made this trainer?

Compiled and QA-tested by the FlingBase team. Game assets belong to Akupara Games.

How fast is the update cycle after a game patch?

We aim for 24–48 hours post-patch. Critical builds are prioritized.

Will this work on a cracked copy?

No. Only the official Steam release is supported. Cracked copies have shifted memory offsets.

Tips Before You Start

  • If hotkeys conflict with in-game bindings (e.g., F1 = help menu), remap the game’s keybinds first to free up the function keys.
  • Anti-virus false positives are common with trainers. The detection is behavioral (memory writes), not signature-based — the file is clean.
  • Apply the trainer only on the Steam build. Cracked or region-specific copies often have shifted memory offsets and the cheats silently fail.

Our Factory 95 Trainer trainer shares many of the same toggles as this build. Worth a look if you are in the mood for another run.

Cheat Options

This robust Kumitantei: Old-School Slaughter trainer ships with 10 fully working options. Each one is memory-driven and toggled from a hotkey:

  • Freeze Chase Timer — Pauses all escape sequence countdown timers.
  • Teleport to Exit — Fast-travel to the chapter or level exit point.
  • No Death Screen — Skips fail-state cinematics and restarts from last checkpoint.
  • Unlimited Keys — Lockpick and key item count never drops below maximum stock.
  • God Mode (Companion) — NPC survivors and allied characters take zero damage.
  • Invisible to All — Complete stealth mode — no enemy can detect your presence.
  • Unlimited Oxygen — For underwater horror sequences — lung capacity meter disabled.
  • No Footstep Noise — Enemy detection relies only on line-of-sight, not audio.
  • Slow Game Time — Reflex-based slow motion toggle activated on demand.
  • Kill Monster Button — Instant-kill the currently active boss or stalker enemy.

Trainer vs. Alternatives

Save editors modify data at rest; this trainer modifies data in motion. The advantage is real-time feedback — toggle God Mode and see the effect immediately, without reloading a save.

Hex-editing save files gives you similar results but risks permanent save corruption. This trainer modifies values in live memory, meaning your save file on disk stays untouched and you can revert changes by simply closing the trainer.
