About
Betrayer is a first-person action-adventure with stealth elements, set in a haunted early-colonial Virginia in the 17th century. It was made by Blackpowder Games, a studio formed largely by Monolith Productions veterans who had worked on F.E.A.R. and No One Lives Forever. The game is known for its striking near-monochrome black-and-white art direction and eerie, mysterious tone, built on Unreal Engine 3. It drew positive notice for its atmosphere, though some reviewers found the combat clumsy; it was later delisted from Steam and re-released for free by the developers.

⚙ Setup notes
Install: Delisted from Steam (appid 243120, removed May 2021), but the original devs (Blackpowder Games) re-released it FREE on GOG in July 2023 — that official free build is the one to use.
Engine: First-person action-adventure on Unreal Engine 3 / UDK.
Proton: Runs well on Linux/Proton; community reports it playing cleanly under Wine-GE / GE-Proton (proton_experimental also works).
DRM: No GFWL/SecuROM DRM to bypass.
Controller: the game ships built-in XInput gamepad support, but it's only partial — community reports note it shows keyboard prompts even on a pad, has no aim assist, awkward menu navigation, and an unmapped/hard-to-bind jump. Plan on a Steam Input layout on the Deck (map jump and add keyboard fallbacks for any unbound menu actions) rather than expecting flawless out-of-the-box pad support.
Note: deckport only configures the prefix; it never bundles or links the game files.
The one thing to know
Supply your own copy: deckport links nothing. Delisted from Steam (appid 243120) but officially re-released FREE on GOG by the original developers in July 2023 — use that build.
Proton: ProtonDB tier gold; community reports it running cleanly under Wine-GE / GE-Proton on Linux, so it should be playable on the Deck (still needs a Deck-specific confirmation pass, hence needs-test).
DRM: No GFWL/DRM bypass required.
Multiplayer: Single-player only, so no dead-server concern.
Controller: built-in pad support is only partial (keyboard prompts on a controller, no aim assist, clumsy menus, jump can need manual binding). Use a Steam Input layout and add keyboard fallbacks for unbound actions.
Binary: Betrayer.exe (UDK launcher); confirm the exact path against your install (engine binary under Binaries\Win32\).

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.
