TIEFGANG is a free co-op roguelite FPS set in 1887. Dive in a heavy brass diving suit, fight through drowned temples, sunken archives and ship wrecks, and build absurd combos from 9 weapons, 95 charms and elemental blessings. Play solo or with 1–4 players in co-op. Made with Godot 4 by a solo developer, free test builds for Windows with automatic updates.
If you like Roboquest, Gunfire Reborn or Risk of Rain 2, this is that kind of run-based shooter, only deep underwater in 1887, in brass diving suits straight out of BioShock, with something Lovecraftian waiting at the bottom.

Tiefgang, Marsh here. Signal’s steady. Below you are the ruins of the Thalassari, the richest Abyssalite deposit anyone has ever found – and something that has been sleeping on top of it for a very long time. Go down, bring back what you can carry, and if you hear a heartbeat that isn’t yours: keep moving.
- Download Tiefgang-Windows.zip – or grab it on itch.io. Older builds live under Releases.
- Extract the
Tiefgang folder somewhere you can write to (Desktop, Documents). Not into C:\Program Files, or the auto-update can’t do its job.
- Run
Tiefgang.exe. Windows will probably say “Windows protected your PC” – More info → Run anyway. The test build isn’t signed.
New builds download themselves in the background and install only in the main menu, when you quit or at the next start – never mid-run. Your saves stay. No internet? The game starts anyway.

A fast first-person shooter built on roguelike runs. You descend through 14 depths of combat rooms, treasure vaults, trials and boss arenas, picking up charms and blessings after every fight, until your build is either unstoppable or very, very funny. Standing still gets you killed; sprint, dash and double jump are your real armour. Between dives you go back to your submarine, research, gear up and go down again – one pressure level deeper.
It’s an indie project in active development. Things change fast, and a lot of what’s in here exists because testers complained about something. Latest round: co-op for up to four, three areas rebuilt to a new graphics standard, redone element effects, 25 new enemy attacks and a mechanic of its own for every weapon. Everything else is in the changelog.
Up to four divers. One hosts, the others type in a room code – over the internet that usually works without port forwarding, and on a home network there’s a LAN code too. Everyone picks their own charms and blessings, shells are shared, and whoever goes down can be revived. Step by step: KOOP.md.

FAQ
Is TIEFGANG free? Yes, completely. No account, no launcher, no ads, no microtransactions. Download the zip, extract it and play.
What games is it like? A fast first-person roguelite in the spirit of Roboquest and Gunfire Reborn, with the build-crafting of Risk of Rain 2 and Hades: fight a room, pick a reward, go deeper, beat the boss of each area. The setting is a steampunk deep-sea expedition in 1887, with brass diving suits that BioShock fans will recognize.
Can I play solo or offline? Yes. Solo runs fully offline. Co-op for up to 4 players works over the internet with a room code, usually without port forwarding, or over LAN. See the co-op guide.
What PC do I need? Windows 10 or 11 (64-bit) and a Vulkan-capable GPU with 4 GB VRAM. Details under System requirements and controls above.
Is it safe? Windows shows a warning. The test build isn't code-signed yet, so SmartScreen warns about an unknown publisher. Click More info → Run anyway. The auto-updater only installs builds from this repository.
Can I stream it or make videos? Yes, monetized too. Just link itch.io/tiefgang. Logo, cover and screenshots are in the press kit.
Which languages? English and German, switchable in the settings.
Found a bug, hit a crash, or think the dash feels mushy? Open an issue – English or German. The version number (bottom right of the main menu), area, depth and a screenshot help a lot. Honest feedback has rebuilt parts of this game more than once.
