English version, used translate:
Created a cooperative server, based on sdk2013, fixed ai, fixed npc, transport, merchant, npc from the portal, npc from episodes (hunters, zombine), a new weapon. Maps from mods Synergy, Obsidian and others.
Server site http://hl2mp.ru
Server address 188.243.54.154:27400
When you first enter the server, the base files will be loaded: models, textures, sounds. The download is long, about 120-170mb, then models and textures are loaded as needed for the map.
Also posted the source and the rest on https://github.com/hl2mp
If anyone has ideas, suggestions for improvement, I will try to fulfill it with pleasure.
