Yes, it is npc pack for GMOD9.
It includes: Gman Kleiner Breen Eli Ithcyosaur Strider(not working perfectly, its stuck in ground if spawned TO ground.) and Stalker
Download it, its great. No need to give credits but if someone asks who made them, please say that I did. Enjoy!
E: Stalker works perfectly, If you have EP1 and gcfscape to extract models outta the gcf file.
