LambdaWars Information.

Lambda Wars is a free multiplayer Source Engine modification for Alien Swarm set in the Half-Life 2 universe that brings the war between mankind and their brutal Combine overlords to a traditional real-time strategy (RTS) setting. Lead the uprising as a commander of the Resistance or crush the rebellion as an overlord of the Combine, with both factions featuring a full host of units, abilities, buildings, research and defenses. Lambda Wars features full-fledged RTS gameplay and a robust RTS interface and is focused on multiplayer but strategic AI opponents and dedicated singleplayer missions are also included.

Previously known as Half-Life 2: Wars, Lambda Wars has been in steady development with a long history of acclaimed public alpha and beta releases since late 2007 and only requires Alien Swarm (free) installed on Steam to play. You also must legally own Half-Life 2: Episode Two. Click here to learn more and get started playing Lambda Wars right now.
