About
Psychotoxic is a first-person shooter in which players control Angela 'Angie' Prophet, a half-angel woman who battles a devil-worshipping cult to stop the Fourth Horseman from triggering an apocalypse. Originally to be published by CDV before that deal collapsed, it shipped in a rough, unfinished state and was widely panned by critics as one of the era's worst shooters. The poor reception and weak sales contributed to developer Nuclearvision Entertainment shutting down in 2009, and the game was never released on Steam or other digital storefronts, leaving it a long-obscure cult oddity.

⚙ Setup notes
Game: 2004 Nuclearvision Entertainment first-person shooter built on the Vulpine/Havok Vision engine — an obscure cult title, long out of print with no active rightsholder presence. Never on Steam, so there is no ProtonDB entry (tier pending).
Install: Bring your own copy. Install normally under Proton (GE-Proton recommended), then apply fixes below. No native Linux build exists.
DRM: CRITICAL — the disc release ships StarForce DRM, which does not work on modern Windows OR under Proton (the developer wanted to disable it for a patch but the publisher refused). You must run a DRM-free/no-CD executable of the same version, and apply the official 1.04 patch first for the weapon-pickup bug and minor fixes.
Cutscenes: the FMV intros use the On2 VP3/VP4 codecs and tend to black-screen / flicker under Proton (on Windows the DxWnd "ForceClipChildren" tweak helps, but that does not carry over to Proton). Simplest fix on Deck: move or delete the cutscene video files from the game folder so playback is skipped and the game proceeds normally.
Widescreen: a community 1680x1050 widescreen fix exists (Vision-engine vbase.dll/vision.dll swap) if you want a non-stretched image on the Deck's display.
The one thing to know
Supply your own copy: obscure, out of print — configuration only, no links. Never released on Steam (no appid).
DRM: must use a DRM-free exe — StarForce DRM is broken on modern systems and under Proton. Apply official 1.04 patch.
Cutscenes: remove the On2 VP3/VP4 cutscene videos to avoid black-screen/flickering FMVs under Proton.
Controller: no native controller support — it's a keyboard+mouse FPS, so bind a Steam Input gamepad-to-keyboard/mouse layout (right stick = mouse-look, face/trigger buttons = WASD + fire) to play with the Deck's built-in controls.

Get the artwork
deckport never hosts game images. Open this game on SteamGridDB, pick
the cover / hero / logo / icon you like, and drop them into the
game folder under .deckport-art/ before you push it to the
Deck. The importer files them under the right names automatically.
Run it on your Deck
Two files: the one-time importer (deckport.py) in your
Deck's home folder, and this game's install helper. Copy the game
into ~/Games and run the helper with Steam closed — it
writes the recipe (binary, launch options, Proton version)
and registers the shortcut with artwork.
