Lambda Wars (formerly Half-Life 2: Wars) brings the struggle between the human resistance and their Combine overlords to a multiplayer real-time strategy setting. The Lambda Wars beta only requires Alien Swarm installed to play. It features 3 multiplayer game modes: Sandbox, Annihilation and Overrun, showcasing the Rebels and Combine playable factions and a full-fledged RTS interface and HUD. There is also a singleplayer tutorial and a handful of singleplayer missions.

The latest update improves Overrun mode and introduces some balancing changes and bugfixes to the HL2:Wars beta.

Posted by Ennui on Nov 28th, 2012

Here we are with another update to Half-Life 2: Wars! The process of small, frequent updates has been working well for us and this latest patch introduces some balance changes, important bug fixes and improves the Overrun game mode by upping the number of enemies and adding some new foes (fast and poison headcrabs and headcrab mortar canisters). Take a look and let us know what you think! We have a lot of interesting stuff in the works that you will begin to hear about in coming weeks.

Many of you have suggested that we apply for Steam Greenlight, and we hear you! We have plans to submit to Greenlight once we pass some internal milestones and get our stuff in order, so it will be a while - but it's definitely something we're moving towards. More on that front later.
