During the opening cinematic, while Hunk's team is being decimated by Birkin, a commando is shown cowering backwards in fear while firing his MP5. On top of the weapon there is a form of red dot sight, possibly an aimpoint. When Birkin impales the hapless commando and the gun goes flying, the scene cuts away to a shot of the gun hitting the ground in slow motion while still firing. In this shot, the scope/red dot sight is no longer present.
The game takes place in September 1998. However, a 2002 BMW can be seen in the first level.
