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.
I hope you'll also improve the team coloring for the other units, as well (Templarfreak's comment to Antlion texture update :D)
Here you are)) the caps of Rebels were too dark before.
P.S. As the new Squad Wars gamemode supports up to 12 players, I made 12 player colors, one of them (bright orange) is showcased here and differs well enough from both HL2 orange and red.
