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, but you must own HL2: Episode 2 on your Steam account. 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.
Played the Beta and i have to say this mod is pure great! Everything in this mod look very nice, impressed me alot even for a beta mod. Hope the future updates will make this mod even better, custom UI, layouts, settings, now Let's compare the graphics, this mod uses original and un-modified textures and models, meaning they're really high-quality, compared to Starcraft 2, this mod has some potential to beat that game, it just lack of some fancy shading that limited by Source
:) keep it up guys, great work
Half life wars transforms one game into an entirely different and wonderfully fun gaming experience as no other mod i've come across could.
Great attention to detail, superb execution, decent balance, multiple in-game options, and a responsive & active development community.
