What was said about Left 4 Dead
Left 4 Dead's AI Director paces the game by each player's intensity. The Director tracks each player's intensity from low health, incapacitation or lots of shooting. At peak intensity it starts a relax phase with no zombie spawns, then builds tension again.
During the relax phase it may add pills and ammo nearby. It spawns mobs and special infected, then pauses them at the peak, so pace is not fixed before shipping. Quote: "they can ebb and flow based on what the player is doing".
Left 4 Dead 2's Director also changes chunks of level layout. In the sequel the Director goes beyond spawn timing and alters parts of the level layout.
