Vu sur les forums de 3DRealms : une interview de Gabe Newell publiée je ne sais où a été entièrement traduite. Finalement, vous n'y apprendrez quasiment rien étant donné que toutes les infos diffusées dedans ont été reprises avant hier par Shacknews. Extrait :

HL2 will make use of what we call "advanced contextual AI", which is best explained as the game world telling the AI interesting things to do in and with the environment. In essence, the gane world 'talks' to the AI, which in turn will react appropriately. Unlike HL, you won't come across any uninterruptible and non-interactive scripted scenes in H2.

An example of the AI in the singleplayer game: let's say a radio is transmitting an important message and an NPC (such as Alyx) heads over to listen. In this situation the player can react the way he or she sees fit - one possibility would be to destroy the radio, which leaves you with a pissed-off NPC. Another example that you have seen demonstrated: you're being chased by a Mechanised Commando and you take refuge in a room close by. You close the door which then 'tells' the AI is can be bashed in and the AI then reacts to this information.
