Half-Life 2: Wars brings the struggle between the human resistance and their Combine overlords to a real-time strategy setting. The Half-Life 2: Wars Beta, which you can download here on Desura, requires you own Half-Life 2: Episode 2 to play (does not need to be installed)! It features 3 multiplayer game modes: Sandbox, Annihilation and Overrun, showcasing the Rebels and Combine playable factions. Additionally it features a singleplayer mission mode.
Shows playing around with the ability system. All abilities are written in python (actually the tool windows itself too and lot of the unit code too). Most of these global powers for the player are only for messing around :)
