I searched but couldn't find a thread on NPC's How about various NPC's that the zombies are chasing too. What would you do if you were in Cherno and an npc child, say a little girl came running down the street with zombies chasing her. What would you do? Ignore her screams for help, she's just and npc? Shoot the zombies and risk drawing attention to your self? Shoot the girl and see what loot she has? You could have all sorts of NPC: Farmers wife with double barrelled shotgun, military survivors, pretty young lady survivors. The number of NPC survivors could be adjusted to the number of real players on the server so low population servers could have more NPC's than full servers. ARMA2 certainly has the AI code for NPC's and the models, it should be relatively easy to implement. Player density is an important variable in the player experience, playing on an empty server is a different experience to playing on a full one. If the player density became more of a constant then the player experience could be fine tuned. What do you think?
