Andrew Whittaker doing some Q+A back in the day:
Q)So, is it true that the original AI for AvP was so good that the Predators went around and killed all the Aliens, thus making the game too easy?
A) I dont know as it made the game too easy having rampaging Predators, but yes
thats quite true. It was fun tho. You could hear alien screams around the
place all the time
Q) How many objects/enemies are actually being tracked and updated in real
A)Everything on the level you are currently on are tracked in realtime. This was the only way to maintain pack strategies wherein all the aliens, marines etc worked in defined groups with well defined objectives. There was over a
couple of hundred strategies per character type. The first one people usually find is “stupid alien” where an alien mills around a room aimlessly,
but is in reality there to distract you from all his pals being on route.
There are loads more. I shall have to discuss them all one day. But the basic point is yes, this is not doom or quake,everything is alive all the
time and plotting and scheming against you.
Q) Why were body armor and the “jump over acid” abilities dropped from the
A)The body armour didnt balance very well in gameplay. The jump over acid was
dropped for two reasons 1) you really have to think about where you kill
things 2) the cart was so full it would have meant dropping something else
to include it.
We (Luca and myself) at Unseen64 have some Q's sat with Andrew,now Jane Whittaker, doubt they will be answered as Jane has contradicted what was previously said on a number of occasions.
I also have another few misc Q's sat with another of the AVP team
