About O2
Manage your oxygen carefully as you navigate the abyss. You descend alone into the dark depths of an unexplored ocean. Armed with only a camera, a map, and a limited oxygen supply, your mission is simple: locate designated coordinates and capture photographic evidence of what lies below. Getting lost, running out of oxygen, or lingering too long in the darkness can turn a routine expedition into a desperate fight for survival. Visibility fades, strange sounds echo through the darkness, and something unseen may be watching from beyond the reach of your light. About This Game About This Game O2 is a deep-sea horror exploration title where every breath matters. Every photograph brings you closer to completing your mission, but also drains valuable resources needed to survive. As you venture deeper, the ocean becomes increasingly hostile. Will you uncover the secrets hidden beneath the waves, or become another lost soul swallowed by the deep? Features Explore a dark and mysterious underwater world Complete photography objectives at designated coordinates Manage a limited oxygen supply Navigate using a map and compass system Atmospheric deep-sea horror and tension Immersive first-person exploration Uncover the mysteries hidden in the abyss The deeper you go, the less alone you feel.

This tested O2 trainer ships with 7 fully working options tailored for the horror genre. Each one is memory-driven and toggled from a hotkey, so you never leave the game window:

- Max Ammo Stack — Ammo stack cap removed.
- Teleport To Exit — Fast-travel to chapter end.
- Kill Monster (Button) — Instant-kill active boss monster.
- Slow Game Time — Reflex slow-mo on demand.
- Unlimited Tape Recordings — Save-tape limit removed.

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 O2 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 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.
- Back up your save folder before the first run. Cheat-induced save corruption is rare but irreversible.
- Run the trainer after loading into a save, not from the main menu. Some games replay the intro with modified memory and glitch.
- Toggle cheats off before scripted cutscenes — some cinematics check HP or timers and can soft-lock.
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 Beyond StarZ update.
Compatibility & Safety
This trainer is built for the single-player mode of O2. Never use it in online or competitive matches — anti-cheat frameworks like EAC, BattlEye or VAC can ban memory manipulation and suspend your account.
