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.
Fixed Antlion textures, they were mixed with the base textures before which resulted in dirty and just wrong colors. That's not the case anymore, and...the bright orange is one of the new player colors, it's quite different from the HL2 'Rebel orange' one!
