Nice spam.
Anyway, from what I've seen the AI is not loaded at all for npc's in multiplayer, they just generally stand around. I even spawned a strider and using ent commands gave it a target and it just sat there and started at me. :-\
I remember hearing right after the binks with it that neither guns were going to be in the final game, but they decided that the Gravity gun was actually useful for combat, the Psygun however was never intended to be in the Final release.
give npc_strider instead of npc_create npc_strider
On a side note, you should set one of the combine in the middle as a target for the striders cannons :naughty:
I think that they removed alot of that content because
1. It was supposed to be a suprise, It was supposed to make you think, and then suddenly everyone knows about it.
2. From what I hear a great many of the things in the leak would have made it very difficult to have the game scalable down...
I was immersed in the game the entire time I played it and enjoyed it while I did so. But once it was over and I had time to think, The story wasn't done right. Sure, they didn't tell you much in HL1, But what they did tell you was very important and stuck with you.
In HL2 you had to guess...
Also, remember Race X? The entire race from op4 that seems to have disappeared from hl2? I think Mr-Fusion is right and the things from Opposing Force were created by Gearbox and aren't really part of the HL story.
