YES there is an earlier thread of this, but this one is updated.
Jingles founded a mod called “Questionable Research”, a mod where you can explore and RP black mesa.
But, because after about a month, there was no coder he gave it up.
Now, i re-took the mod and I am looking for these main positions(these are most important).
Lead Dev: A good leader who also has a skill like mapping, face posing etc.
Coder: A CPP coder
Mapper: a Source mapper
Concept Artist: A guy who can draw(draw GOOD)
Texture Artist: This is important!, a guy who can make textures!.
If you can apply in one of these roles, please sign up at the forum and report at Civilian Recruitment Division:
questionablemod.hlmods.com
If you have an other position that could be useful(voice actor, face poser n stuff), check the forums too.
