Cool... In HL1, I loved spawning Marines on one side of a map and Aliens (Shock Troopers) on the other, thow a nade near one group and watch the action... :stare:
yes, currently a function npc_creat did not work, but you can type give npc_barney and then retry and you will have a barney npc and the map will be the way it was before you retried.
In steam spawning does not work for me but in Vanilla HL it worked and I had a blast. You use the give cheat and go to the VERC website to find out the name of the entity you want to spawn.. you can spawn it only if the entity is on the map your on... cuz the game will crash.
Just make a simple map with obstacles in it, and then stuff in as many marines as possible. Really cool to make a map with female assassins in the middle, in a large room filled with pillars and in each corner a func_monstermaker which created zombies. Make an indestructable glass room for yourself ofcourse
