Vidmaster Challenge: Annual

Vidmaster Challenge: Annual

After 9/25/08 you must complete the mission Halo on Legendary difficulty while playing on LIVE co-op with four players, including yourself.  You must have the Iron skull activated, and you must all complete it alive, in Ghosts!  Here's how to do it! ~ Beginning of mission: Have each person grab some weapon ammo, make your secondary either a Rocket Launcher, or a Fuel Rod.  Your primary weapon should be a powerful weapon of your choice with well over 100 rounds of ammunition, such as a Battle Rifle.  Try to disperse the weapons and ammo to your friends as well as you can, making sure each of you has ample ammo to wipe out the first wave of Covenant.  Once you have your weapons and ammo, proceed through the cave towards the battle field.  Note that having the Iron skull activated means that anytime even one of your teammates dies, you will all respawn at your last checkpoint, so be careful and try not to die.  Once you get to the battlefield, I suggest that you turn right and climb up the hill near the exit of the cave so you have a better vantage point.  Have the two weakest players up there, and the two strongest down on the ground.  Take cover and don't let your health get too low, or you will be very vulnerable.  Once you have wiped out the first wave of Covenant, proceed onwards around the right of the Arc.  This is the second wave, be careful and take cover as to not be killed and revert to the last checkpoint.  From this point you will just have to work your way up the ramps until you reach the top, but I suggest you stay on the edges of the platforms, so it is easier to take cover and restore health.  Once you reach the top, it is quite difficult to hold off that point until the door opens.  Hold your positions and try to attack from behind if possible.  Once the door is open, run through the building until you get to the last door.  Spark will try to kill you and push you off the edge of the bridge with a large orb-type ray, so just wait it out and stay near the center up against the door until the Chief can give you his Spartan Laser.  Whomever is best at using a Spartan Laser should take it from the Chief and kill the Monitor.  Deactivate the dang thing and get the hell out of there!  Be careful once you get to the exit, either let the Sentinals pass, or kill them on the spot.  Once exiting the building go down the ramp to the left, and under it are four Ghosts.  Take them and go back up the ramp and over the snow mound.  Eliminate the last of the Covenant and Sentinals and go through the building taking out anything in your path.  Once you exit the building and pass Johnson's Warthog, turn right and follow the path out!  You will reach a vast area of platforms that explode and collapse without warning.  Follow your radar and do your best to avoid exploding and collapsing platforms.  Once you get to the checkpoints, which are huge maze-like platforms with a Warthog on each one, do not stop.  Proceed as fast as you can and you will enter large tunnels with three different paths.  All four of you must stay close together, one right behind the other, at all times, and take the same paths.  Once you reach the tunnels, choose a path and try to bear to the right.  Each time you exit the tunnels you will find yourself upon a new set of exploding and collapsing platforms that lead to more tunnels.  Once you exit your last tunnel, the platforms will take you around a curve to the right, then around a rock structure to the left.  I suggest avoiding ascending the hill at this point, and veering right after you curve left around the rocks.  Follow this to the end and jump off the center ramp.  You've done it!
