- A situation GameStar experienced regarding the A.I.: While being chased by two enemies in a building they ran to an upper floor. The two enemies followed them. Reaching the floor, GameStar had to jump from a wall onto the ground because there was no other way out. One of the NPC stalkers noticed this and started to shoot at the editors and distract them while the other NPC stalker ran down the stairs again to the first floor to catch the editors and shoot from that position.
- In main quests there will be a "scripted" path of actions, Andrew explains: "In one of the missions you have to infiltrate the stalker-base. To simulate a regular camp life we use scripts. However, as soon as you trigger the alarm the combat AI appears and your enemies act from now on independently."
