- New Camera - We've added a new camera mode to the game. Lovingly
dubbed the EQ Cam, it uses the mouse wheel to allow you to zoom away
from your character into a "chase" camera. This only works from first
person mode (the default view). Using the mouse wheel you can determine
the distance of the camera from your character, or to zoom back into
first person mode. When in the chase mode, mouselook turns the
character and camera together and you can change the pitch of the
camera using the mouse.

If p99 wants to be as authentic as it should be, mouse zoom shouldn't be a thing here either.
