Beyond All Reason

Beyond All Reason (BAR) is a free and open-source, community-made
real-time strategy game built on the Recoil (Spring RTS) engine, with
original open assets. This snap packages the official BAR Lobby
(Electron-based launcher/client), which handles logging in, matchmaking,
and downloading/updating the Recoil engine and game content on first run
and whenever new versions are published.

Because the Recoil engine and BAR's maps/game content are updated
frequently and independently of the lobby release cycle, packaging the
official launcher (rather than freezing an engine/content version inside
the snap) is the most maintainable approach, matching how the upstream
project itself recommends distributing BAR.
