Hello everyone, I'm uncle goose, the author of Lambda project.
What is Lambda?
First of all, this is a platform for mods, which will create more beautiful mods for Half-Life.
What is done?
Added some of the weapons to the Xash Weapon System, this will allow you to specify your weapon parameters.
Added high-resolution environment textures.
Added static models from Black Mesa (need fixes)
Yes, it is possible.
It remains to add some weapons and models for monsters.
How to help?
Try to port monsters from Black Mesa to the skeletons of Half-Life monsters. Or port weapons from Black Mesa.
