Cross-era Command & Conquer total conversion. Standalone OpenRA portable — stock OpenRA not required.

That One Thing
It strips away thirty years of sluggish clunkiness from classic Command & Conquer while keeping every ounce of the razor-sharp RTS pacing intact.
Combined Arms mashes Tiberium, Red Alert, Dune, and later C&C factions into one competitive OpenRA client. It ships as its own Windows portable from Inq8/CAmod; you do not install stock OpenRA first.
PlayBound's default OpenRA edition stays the official portable. This edition is the CA winportable: CombinedArms-*-x64-winportable.zip from GitHub releases. ModDB remains the project news page. The Combined Arms row on the Mods tab is left in place for anyone who already installed it that way.
