Half-Life 2 real-time-strategy game mod Lambda Wars has finally left beta and launched proper on Steam – 13 years after development began.
Lambda Wars is a free standalone multiplayer mod for Valve's 2010 multiplayer top-down shooter Alien Swarm (which is itself a remake of a mod for Unreal Tournament 2004) set in the Half-Life 2 universe that brings Valve's first-person shooter masterpiece into the RTS genre.
You play as either a commander of the Resistance or as an overlord of the Combine, with both factions including units, abilities, buildings, research and defences.
