SWAT 4 Gold Edition

Install method (GOG)
SWAT 4 is no longer sold on Steam — buy SWAT 4: Gold Edition on GOG. Install it with
Heroic Games Launcher (or Lutris). In the game's settings within Heroic, set the Wine
version to Wine-GE-Proton8-26 (download it via Heroic's Wine manager if not already
installed). Stock Proton Experimental also works for many users.

Which executable
The Gold Edition installs two separate executables in the GOG folder:
- Base game: Content/System/Swat4.exe
- Stetchkov Syndicate expansion: ContentExpansion/System/Swat4X.exe (set as the binary here)
The expansion (Swat4X.exe) loads its own front-end and includes everything from the
base game plus the seven Stetchkov missions, melee, VoIP, and extra gear — so it is the
recommended launch target. To play only the original campaign, point the binary at
Content/System/Swat4.exe instead.

ProtonDB / Deck status
Reported as Gold/Platinum-class — the game runs very well under Proton/Wine-GE with no
major workarounds. Save/settings write issues that plague modern Windows are generally
not present under Proton's per-prefix filesystem.

First Launch
On first run the game may show a compatibility warning — dismiss it and proceed.
It should reach the main menu without further configuration.

Controller
SWAT 4 has no native controller support. Add Heroic (or SWAT 4 directly) as a non-Steam
game and apply a community Steam Input layout, e.g. the SteamDeckHQ-recommended
"SWAT 4 Keyboard (WASD) and Mouse" by skatebakethreash, found under the Community Layouts
tab. It maps the many keyboard bindings onto the Deck's buttons and trackpads. Takes a
little adjustment but plays well.

Display / Performance
Holds 60-90 fps easily on Deck at very low power (~8W) thanks to the game's age. SWAT 4
is a 4:3-era title; 1280x1024 with Render Quality "Very High" is a good preset. Native
1280x800 (16:10) also works. No TDP lock needed; long battery life (6+ hours on OLED).

Optional: SWAT: Elite Force mod
The community "SWAT: Elite Force" overhaul (and its successor the SEF Community Mod) is
the most popular way to play. Install over the GOG copy: drop the SEF folder into the
SWAT 4 install directory WITHOUT overwriting your existing Content/ContentExpansion
folders, then launch via "Launch SEFMod.bat" / "LaunchSEF.exe". On Deck you would point
the Heroic/non-Steam launch target at that launcher instead of Swat4X.exe. See the
eezstreet/SWATEliteForce and SEFCommunityMod GitHub repos.

Multiplayer
The in-game GameSpy master server is dead; online play today goes through GameRanger or
direct/LAN connect. In GameRanger point SWAT 4: Stetchkov Syndicate at Swat4X.exe.
Online play on Deck is untested here — the single-player/co-op campaign is the focus.

Audio
If voice-over audio is missing or crackling, prepend to launch options in Heroic:
