 Binary counter
 
 In the Great Pyramid stage, just before you enter the pyramid, you 
 may have noticed a panel above the entry with alternating I's and 
 O's. This is a timer counting down in binary. The timer starts at 
 1,023 and goes down from there.
 
 
 
 Defeating the final Boss
 
 After going into the great pyramid, find the obelisk room. It will 
 then rise. Keep walking around until you see an FMV sequence. You 
 will then go to the place where the Boss climbs up the wall. Beware 
 -- this Boss has the most powerful spells and weapons. After he/it 
 shoots, run to the jump ramps. Jump/boost through the power rings 
 clockwise, and when you are next to the jump ramps, preferably by 
 the backpacks, start unloading with the Lasergun. That weapon will 
 drop him down to a quarter of his health, but only after 800-1200 
 pulses. Note: He can regenerate health. Also, when at the Great 
 Pyramid and the door has not opened, pull out your canon and start 
 shooting the Boss in the head. Take out your minigun frequently 
 to take out Kleers, Biomechs, Werebulls, etc. Then, when he is down 
 to red, go inside the pyramid and look up. There are four triangle 
 objects that light up and make strange noises once you jump through 
 the ring things that have lights in them. To activate the teleporter 
 you must use the super jumps (all four) and you will automatically 
 jump through the ring things. However, you must make sure that the 
 Boss is on the lighted up center. Once you have jumped through all 
 four, look up and you should see four blinking triangles. This will 
 take some time, so make sure you have him in the lighted up circle 
 in the middle of the pyramid. If he is still in red when the teleporter 
 is on, and it hits him, he will die.
