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.
Demonstration of the annihilation gamemode. In this gamemode you must destroy all enemy hives to win the game.
Repeated textures... I don't know what else you could do.
Use more 'zoomed-out' textures at a larger scale.
Anthilation!
if the ground is too busy in rts's its difficult to make out the troops so, awesome ++ for repeating textures
