Lambda Wars is now a free standalone mod on Steam: Steam Store (December 2014)

Lambda Wars (formerly called 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.

As of December 2014, we have released the game on Steam as a free, standalone mod. This means you DO NOT require Half-Life 2, Alien Swarm or any other Source game to download and play Lambda Wars on Steam.

For questions, comments, suggestions, and support for any of our past or upcoming betas, visit our forums or steam community hub.

Last Wednesday we released our biggest update yet! This update includes three new units and two new buildings, many balance changes and improvements.

First off we replaced the Rebel Partisan with an updated version. This unit has two main attacks between which you can switch: throwing molotovs or stinkbombs. Molotovs do light damage at units around the target area, while stinkbombs slow units down. Second we got the new Riot Metro Police, equipped with a shield and stunstick. In offensive mode, this is a fast moving melee unit. Using the station ability you can deploy the unit, generating a cover spot for units behind the metro police.

Furthermore we added the Rollermine to the Combine, which you can produce at the also new Mechanical Factory building. The Rebels got a new Offensive building, the Teleporter. Using this building you can teleport units to anywhere on the map, as long as you have vision. A teleportation takes 40 seconds to complete. During this time the units being teleported are unusable and rift is created at the target location, visible to enemies.

I know what I say spoils the game balance, but it would be cool to have on the Alliance adopted by all types of vehicles (armored personnel carrier, helicopter, attack, transporter). After all, for the rebels, too, can come up with something.
What do you think? Sorry for bad english.

I feel that the Sandbox editor needs some improvement aswell. It is fun to be able to place objects anywhere you want and mess around, but players should also be able to save custom, modified/created maps for use in other gamemodes. This would probably be helpful considering some may want to continue their work after a match. Anyone else agree? :D
