L4D 2 features �The AI Director 2.0� which expands the Director’s ability to customize level layout, world objects, weather, and lighting to reflect different times of day. AI Director 2.0: Advanced technology dubbed �The AI Director� drove L4D’s unique gameplay – customizing enemy population, effects, and music, based upon the players’ performance.
Each of the five new campaigns contains at least one new �uncommon common� zombies which are exclusive to that campaign.
L4D2 promises a satisfying and uniquely challenging experience every time the game is played, custom-fitted to your style of play. This improved Director has the ability to procedurally change the weather you’ll fight through and the pathways you’ll take, in addition to tailoring the enemy population, effects, and sounds to match your performance.
