They should add a skull thing like halo where you chose ur modifiers and the more you have, the better rewards you get

The Final Countdown: failure to revive a team mate within 30 seconds will result in a Mission Fail.

[i]Minion Birthday Party[/i] Killing the lowest ranked enemies (Dreg, Thrall, Goblin, Legionary) causes them to explode in a shower of confetti.

Pitch black: darkness fills the area, making it impossible to see. At the spawn location is one flashlight. One player can choose to use the flashlight, but then can't use his/her weapon and has to shine light for the others to shoot.

Mad Bomber: Enemies chuck grenades as their primary means of attack.

Some of the class-specific perks can make good modifiers: Gunslinger's Trance: Precision kills increase weapon stability for a short time. Twitchy: Melee cooldowns are greatly reduced. (Based on Fast Twitch) Other ideas: For Honor: Defeating the Boss doesn't end the mission (Enemies that are alive must be finished off) Fireworks: All weapons deal Solar damage, kills from Solar damage causes players/enemies to explode Arc Shock: Arc damage from any source has a chance to cause stagger and blindness Void Vacuum: Causing Void damage reduces incoming damage from other sources for a short time (Player and Enemy) Alien Technology: Wield the weapons of the Darkness (Do the mission using only enemy weapons) Minefield: Standing still for a short time causes the player to explode Edit (1): Income-based Modifiers (Glimmer earning items must be activated): Pickpocket: Causing melee damage has a chance to earn glimmer; taking melee damage has a chance to lose glimmer Blood Money: Kills with precision damage earns twice as much glimmer Bankrupt: Dying causes you to lose all earned Glimmer Wanted Dead: Killing an Ultra with precision damage earns four times as much glimmer Charity: Reviving a teammate earns a small amount of glimmer Life Savings: Glimmer earnings from all sources increase for every minute of no damage taken Coherency: All decoherent (blue) engram drops have a chance to be a Strange Coin, a Mote of Light, or 200 Glimmer Break the Bank: Kills from Supers earn extra Glimmer; collecting Orbs earns glimmer Edit (2) Character Ability Modifiers: Blink: Makes the equipped jump ability Blink Lightning Blade: Melee abilities and damage do considerable Arc damage Brick Wall: Melee damage from any source is reduced to 0 Pugilist: Kills from Melee abilities reset Melee cooldown Eagle: Makes the equipped jump ability Glide Nuked: Damage from grenades instantly kill (players and enemies) Minesweeper: Kills from Melee or Grenade damage has a chance to kill the player or all nearby enemies

Aura of Fear - all enemies run away and make it really annoying for you to kill them

[b]Eye for an eye[/b]: If you kill an enemy you have a slight chance to die instead of the enemy. [b]Revenge:[/b]If you kill an enemy they have a chance to come back as a higher tier enemy (if they did a 2nd time they stay down). [b]After Shock:[/b]If player has been hit with an elemental attack, the element will begin to damage the player over time (depends on player level, enemy level). [b]Ka-boom:[/b]all grenades have increased damage and blast radius. [b]Kamikaze:[/b]when a enemy is near death or is killed they will exploded causing damage to anyone within a certain radius.

LUFTWAFFE - in outside areas, enemy ships patrol the area and fire at you constantly. ELECTRO-MAGNETIC STORM - would cause your radar to behave weirdly/freeze/go dark at times. SKIPPED MAINTENANCE DAY - guns would sometimes jam for awhile. ...and of course the best one has already been said: friendly fire. That would be great. Especially if it applied to enemies too. It would be lovely if Bungie would allow us to make our own custom missions/strikes at some point, and the rewards would be calculated accordingly. My choice would be: - Nexus, lvl24 - Heroic - Friendly fire (for enemies too) - Electro-magnetic storm - Skipped maintenance day

Ball Buster: Pay 15,000 glimmer to put a curse on a player for 24 hours which makes them only get green engrams, nothing higher

Half full/half empty: Only half a magazine can be loaded at a time.

[b]an absence of light-[/b] You screen fades to black just like in segments of the vault of glass while you are in darkness zones. Only way to restore your screen is to do one of the fallowing. [spoiler][u]Shoot your gun[/u], which meens darkness would form prety quick and only will be partaily dampened each shot, besides rockets and snipers [u]Use ability[/u], weather it be super, melee special, or grenade Or it could be a specail form of black eye from halo [u]melee[/u] is only way to clean your screen Feel free to reply with an opinion of what you like best out of these options, or have one of your own[/spoiler] [b]TWCFTM!-[/b] For all that don't know, "That wizard came from the moon" it would be like IWHBYD, but since no enemy's speak english, instead any line from your ghost is swapped out for new ones often derpy or humorous. And yes it would put that line back into the game as well. Examples of a line... Actual spoilers here [spoiler] As your on mars first time mission were ghost sets off alarm being cocky. You go through doorway, ghosts says, "whooooa ah, was that a magnetic lock!! -odd electrical sounds occur with sparking-" "Never mind that put me on the terminal" -ghost voice seems odd and sorta slurred like he's drunk- You as always do as dinklige tell you and set him out "Whoa do many buttons, -beeping sounds- What hapens if I press all of them at once??" -alarm sounds end scene[/spoiler] TWCFTM would most likly be used in daily missions for fun. [b]RNG forever!!-[/b] Only way to restore heath is through a health pack system... Of what you ask? Ammo types! If you pic up a white ammo drop small heath restored, special probably near half or half, heavy near full restore. Ammo synths would give you no health [b]If only I had A Super-weapon-[/b] [spoiler]Another random exert from halo much like IWHBYD. [/spoiler]With this modifier on you would have no access to your inventory... "But what ever do you meen no access to our inventory Squizzlor??" Im talking no swapping or upgrading gear, no changing classes or editing them, no ammo synthesizers, and yes not even your money earning equipment! Best come per paired cause the ball is played as it lays [i]Hope you enjoyed my modifiers feel free to comment![/i]
