This mission actually almost took us longer then Halo 2 Gravemind LASO. The start of this getting to the first tower was very rough.
Iron "Death carries a heavy price..." If you die while playing solo, you will respawn at the very beginning of the level and the "Revert to Last Checkpoint" option is no longer available. If any player dies while playing Co-op, all players will be reset to the last checkpoint.
Black Eye "Bash your way to better health."
The player's shields will only regenerate by performing melee attacks. The Energy Sword and Gravity Hammer's RT attacks, the shockwave created by the Gravity Hammer's swing, and hijacking also count as melee attacks and will recharge your shield.
Tough Luck "Your foes always make every saving throw."
Enemies will more often successfully dodge grenades, weapon projectiles, and vehicle splatter attempts.
Catch "Pull pin. Count to three. Throw."
All AI-controlled units, friend or foe, throw grenades more often and have unlimited grenades. Even scripted grenades are affected: on the level Crow's Nest, the Warthog will be destroyed by up to four Plasma Grenades. The Skull has no effect on Flood.
Fog "You'll miss those eyes in the back of your head…"
Your motion sensor is disabled. (Redundant since Blind is enabled)
Famine "Trust us. Bring a magazine."
All weapons that are dropped by enemies or are scripted to spawn on the ground (e.g. near a crashed Pelican or group of dead bodies) have reduced ammunition or charge. However, weapons found in cases still have the normal amount of ammo.
Thunderstorm "Field promotions for everyone."
All enemies and allies are promoted to the highest available rank. The number of shielded Flood Sangheili Combat Forms and shielded Sentinels is increased.
Tilt "What was once resistance is now immunity."
All enemy weaknesses and resistances double. For example, Jiralhanae armor is twice as weak to plasma weapons and twice as strong against projectile weapons.
Mythic "Coverage under the Covenant Health Plan."
All Covenant enemies have twice the amount of health.
Blind "Shoot from the hip."
Your entire Heads-Up Display is disabled. You can't see your weapon, shield meter, motion sensor, or ammo/grenade count.
Grunt Birthday Party "Light a match…"
If an Unggoy is shot in the head with any headshot-capable weapon, a popping sound plays, a sound of children cheering plays, and colorful confetti explodes out of the Unggoy. The confetti explosion causes minor damage to nearby enemies.
Cowbell "More bang for your buck."
Explosions and melee attacks launch characters and objects farther, but the damage is not affected.
IWHBYD (I Would Have Been Your Daddy) Skull "But a dog beat me over the fence!"
Unlocks new and often humorous dialogue for the AI.
