Perfect Dark (N64) Easter Egg - Any Questions?

-Enter the Combat Simulator and go into Advanced Setup. Select the Warehouse arena and start the game.
-When you spawn in the arena, make your way to the main area (there's a big pile of creates). Climb up to the top cat walk around the outer wall and find one of the three entrances to the air ducts.
-Crouch down and enter the vent, then crawl around to the junction box where there is a weapon spawn site.
-Being careful not to fall down the hole in the floor, stand up and look up at the ceiling above you. You should see a vent with an inaccessable ammo create on the other side. -If you look at it from the right angle you will notice a question mark (?) cut out of the grate that the ammo is sitting on.
NOTE: The angle you look at it from makes no difference to it's visibility, you just might not notice it at first or mistake it for a rendering glitch.
