Thanks, Cristiaan, for the heads-up. CSPORTS has happened to have snuck up a new review of Quake 4, providing quite a furnishing, fresh perspective on the game for those unfortunately disappointed folks, hardcore, seasoned Quake fan veterans and/or newbies alike. Here's a rather abrupt snippet:
"The A.I. in Quake 4 is very satisfying. In some sequences, you fight together with your squad mates and you must prevent their death at any cost. Maybe you'll think they are invincible at some points, but they do die. If you leave some main characters on their own, they will die and you will lose. You will encounter medics and engineers on the way, use their services free of charge. Some sequences include vehicle and/or some mounted weapons control."
