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 game startup screen is now the lambdawars.com website background art by carbongo! You can see it in the dev branch.
When single player?
No, when you start the game from Steam.
Would be nice if both could cycle since the original is still pretty cool lookin'.
To me the original looked strange by Rebel and Combine soldier covering each other's backs, and they both had AR2s in it. Maybe some other dev who knows how to randomize the loading screens will find your idea good.
