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.

Beta 2.0.6 features a host of visual improvements, including new models, textures, animations, and HUD/interface elements on top of the usual bugfixes, code improvements and balancing changes.

Posted by on

The latest update to Half-Life 2: Wars brings a lot of visual improvements to the mod in addition to the usual host of balance changes, code improvements and bugfixes. Our newest developer ProgSys has been hard at work improving the graphical side of the modification and thanks to him we have improved models and textures for control points, manned turrets, the Combine sniper rifle and more, including a building animation for Engineers. Lt_Commander has also created a bunch of updated interface icons and HUD elements which are included in this release.


The map hlw_forest has received a visual update, and the other maps have also been updated to take advantage of our new multiblend terrain shader. You can see a lot of the graphical improvements in action in these screenshots:

Any chance to add group units formations?

Line, Column, Wedge?

Reply Good karma Bad karma+2 votes

I'm sure they wil be added in a future update.

But I wont be full sure.

Reply Good karma Bad karma+2 votes

To be fair, these aren't Medieval times. I don't see units shooting their SMG's conveniently in a Wedge formation.

Well the fighting in this doesn't exactly show modern times either.

Too late, I've already lost interest for HL2:Wars when they removed Rebels and added Antlions as playable "fraction". Even when Rebels came back now, I wont check it.

It's up to you. Rebels were never "Removed" we decided to rebuild the mod again and we used the Antlion faction as a demonstration of our new work.

Why would you NOT like a faction addition?

Still hating the firerate and the AI, please go back to the hl2 AI used in 0.5

Reply Good karma Bad karma+3 votes

But Please make an Easier "Scenario" Mode.
Sandbox is too... somewhat boring or weird!

Is this something like OverWatch, just no player vs AI?
