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.

As a Half Life 2 fan since it came out, I always wanted to get a taste of playing on the side of the combine, and playing in the Half Life 2 universe as an RTS.
And I must say... Half Life: Wars delivered.
The Pro's were that it was built on the source engine, so everything is basically the same as the original game. Blood, sound, ragdolls, etc. You were able to switch sides between rebels and the Combine, along with being able to construct every character you meet in-game (along with a few other surprises). The soundtrack was pretty bomb, and it plain feels wonderful being able to take down a rebel base in the name of the Universal Union.
The only con I found that almost put me off the game was that there is no AI difficulty option. As I played, the AI was relatively easy, with a few surprise rushes on my poor Metro Police that ended with me losing several control points.
This mod might seem reminiscent of Company of Heroes to some (like me), but it brought a sense of comfort knowing exactly what I need to do.
TL;DR This is an amazing mod and I recommend people try it.
