Title says it all, be sure you use: Steps/objectives about campaign level important details about missionvehicles along the way, certain enemies, etc. etc.) Maybe even details about a thought up vid that comes before the mission. (trailer) Where mission takes place. (reach, ark, halo.) weather. (duh) Other than that, be creative. maybe even use some pictures to help explain. begin Mine was taken from another person, A mission where you are on an elephant with a couple of marines, driving slowly thru flood territory, your 1st objective is to get to the elephant after your pelican crashes, 2nd objective is to protect the engineer while he repairs the decomissioned elephant. 3rd objective is to hold off the flood while your driver, who is protected by a marine with a shotgun, drives to a safehouse unsc bunker, where you will meet with Lord Hood and other UNSC Staff to plot your next mission for evac. You are free to roam about the elephant, having it be exactly like a regular elephant, except with more firepower, you should stay on the turret, protect your driver and the other UNSC officers and soldiers. You leave the elephant, you get left behind, and you will more than likely die very quickly. That is mine" Begin
Mine takes place inbetween Sierra 117 and crows nest (Ilike coming up wih alternate missions/fller missions) You get shot down on the way to crows nest,and nobody but you and Seargent jhonson,and the arbiter survive,after traveling through the jungle abit you come across a secret covenant camp,when they are making a plasma gun to shoot down the base,when you eliminate them,you must destroy the gun,and when you do,you attract abunch of attention,instead of eliminating all of them,they hiJack a spectre (only one in the game) and make a run for it. after a cut seen you come up on a squad of worthogs,and get a ride from the marines. after getting near the base,you come up on an invasion force,getting ready to attack the base,then you make an attack. you take on the whole force (about how many enemys are in crows nest) you must beat them all (dont worry six worthogs and tons of ammo around the covenant base,from fallen pelicans etc,etc) yuoll be fine. then the whole group of you find alot of them excapted in phantoms. ill probobly post more later.
i have another small one: MC, seargant johnson, and the arbiter, along with a bunch of marines, are traveling thru a jungle in a group of warthhogs, you have to hold off multiple banshees while getting to certain possitions and arming mines/remotely controled explosives/w/e, on covenant anti air, your sitting in the passenger seat, with infinite ammo for your rocket launcher. thats all i could come up with
