He stopped supporting the mod I believe

you alive ?

From BM Military recruits from the training camp without armor - useful for hostile and friendly deserter soldiers.
and from Damocles, that guard with the newfangled gadgets, Daniels or whatever his name is.
And also equipment: a cargo helicopter from the blue shift, guard cars in various colors, Bradley's btr on rails or stationary from the Azure Sheep.
We could also add a scientist in a cleansuit from Azure Sheep.
and new skins for aliens: classic and Revamped (for hostiles in chapter 14 at the beginning and end) and at least one live hev scientist or hev guard in Xen

Speaking of personnel expansion for IMPROVED MESA + CLASSIC XEN COLORS you can add not only from Black Mesa Character Expansion (as well as Black Mesa Character Expansion Revisited) but also from the modifications : from blue shift workers and their zombie versions, Otis with his voiceover and Murdoch, soldiers (provided they were not taken from Black Mesa Character Expansion), from azure sheep: black operatives (for them maps bm_disarray and Communications Detour add in the surface tension and helicopter black) , female guards (including Kate) , human assassins (there are different variations) , maybe agents from the end of the first part;

I meant why is there no mod called classic xen colors... But I wanted to be funny which failed.

@Wyatt The Sans
what do you mean?

Why no classic xen colors?

Perfect
