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.
Combine uniform has camo stripes and spots (more visible on regular soldiers' uniforms and less visible but with the same geometry on elites' and shotgunners' ones), so why not use some of them to improve team color visibility?
Bad idea, they look terrible. Let Combine stay the same as before.
I think I need to see this from the top-down RTS perspective to be certain on anything. As it stands right now, I think I'm pretty indifferent to it.
Серый Anything can look bad from this perspective for an RTS, but when viewed from the traditional RTS perspective it can look totally fine.
You're right, updated, I should have used this view initially as I did for Rebel caps.
It looks like this team coloring would be quite visible, although this is still pretty zoomed in, from this angle I think it works. It doesn't look as natural as the rebel caps, but it's definitely more than passable.
