To build a trap in Halo 3 you go into the forge on Foundry and build an active camo. Next, surround it with 3 dumpsters and set a man cannon behind the active camo against one one of the dumpsters. Finally, build a dumpster behind the active camo and in front of the man cannon. When someone takes the camo, the dumpster will splatter them. Enjoy!
about the same as the memorial at the end of halo 3 :D
Slaves used ropes used ropes and ramps to build the PYRAMIDS , as the stones [building blocks of pyramids] were too heavy to carry with hands or on their backs.
www.wheelchairramp.org has information and a manual on how to build them. There is also www.wikihow.com/Build-a-Wheelchair-Ramp
