Part 1: Bypass RedKard Anti-Cheat (sorry devs... we promise we won't actually cheat)

1. On the Steam Library page for the game, press the cogwheel icon, then hover over Manage and choose Browse local files.
2. Rename launcher.exe to something else that the game won't recognize.
3. Rename PortalWars2Client.exe to launcher.exe.

Part 2: Replace the Microsoft Visual C++ Redistributable Installer

This step can be skipped, but you'll have to install and uninstall UE Prerequisites at every launch, and when it's an uninstall cycle you'll have to close the game to get an install cycle. This will allow you to just press "Repair" instead.

1. Go to aka.ms/vs/17/release/vc_redist.x64.exe (we can't post URLs :sob:).
2. Still on the Local Files from earlier, go to Engine/Extras/Redist/en-us and replace UEPrereqSetup_x64.exe with the file downloaded on the previous step (the name must be changed to "UEPrereqSetup_x64.exe").

Part 3: Proton version and Launch Options

Option 1: GE-Proton8-32

1. Use an utility like ProtonUp-Qt to download GE-Proton8-32.
2. Exit Steam.
3. In ProtonUp-Qt, press Show game list, scroll to Splitgate 2 - Alpha, and in the Compatibility Tool column, choose GE-Proton8-32.
4. Reopen Steam.
5. Press the cogwheel icon, then choose Properties.
6. In the Launch Options textbox, put -dx12.

Option 2: Proton Hotfix

1. Press the cogwheel icon, then choose Properties.
2. In the Launch Options textbox, put -dx12.
3. In the Compatibility tab, check Force the use of a specific Steam Play compatibility tool.
4. In the dropdown, choose Proton Hotfix.

Optional thing, just to make sure.

1. Open Steam in Big Picture Mode.
2. Select Splitgate 2 - Alpha's page.
3. Press the cogwheel icon, then Developer, and choose Delete Proton files.

Known issues, unfixable so far.

• If you Alt+Tab out of the game after or during a match, your game will crash at some point. Do not Alt+Tab ever until you're done with your Splitgating session. The cause of this issue is unknown. The reason why Alt+Tabbing could ever cause an issue is even more unknown.
• Playing in a party won't work. The game will crash for all members when the countdown for the match you're playing starts. The cause is unknown: current hypothesis is that it could possibly be the only server-side Anti-Cheat check.
