Have you ever thought your actions were really controlled by some invisible entity with the power to make your life considerably better or worse?
Exploration 1: The first time through here, it was quiet … too quiet.
Well the A.I. Director is just like that. Throughout every game mode, most noticeably during campaigns, the placement of every inventory item, weapon, object you can carry, certain routes you take, and enemy incursion is determined procedurally to provide you with a unique experience each time you play a game.
Exploration 2: The second time through here, it was madness! Sheer madness!
This basically means that whenever you find a Safe Room, the weapons may (or may not) be the same. It means that the item placement icons shown in this guide’s many maps are possible locations; the item may not appear every time, or be the same kind of item every time. Aside from locations where Hordes are always summoned, the number and type of enemies changes dynamically each time you play and is never the same twice!
With this in mind, the guide’s Walkthrough has noted any major A.I. Director decisions that drastically affect your tactics (such as locations where car alarms may sound, or where routes change).
The Director tailors the gameplay experience depending on how well you’re doing; for example, it sends in additional foes or Special Infected if you’re playing competently, and reduces the number of First Aid Kits.
Of course, sometimes it’s just plain nasty, and throws in a Horde when you’re least expecting it. Remember this when you’re adventuring, and when reading this guide’s Walkthrough.
