NOTES: Highguard is unplayable on SteamOS due to Anti-Cheat and requiring Windows 11 and Secure Boot.

By default, the Steam Deck does not have the ability to enable secure boot through the BIOS with signed keys and requires using a 3rd party tool to achieve this which is currently in an experimental beta phase.

Once we have Highguard running, the game requires Low settings and a 35% Render Scale, where the game causes the Steam Deck to completely crash after 20 minutes of playing, making most matches unable to finish.
