A rebalanced overhaul of the Halo 2 Campaign. Including weapons and vehicles that feel more in line with their Combat Evolved counterparts, such as the Plasma Pistol doing actual health damage with its overcharge with EMP as a side-effect, and the Player having both Decent Shields on Legendary AND a visible Health Bar. Enemies and Friendly AI have been rebalanced as well, with Elites having more health across the board, Brutes being less bullet-spongey but still dangerous and tough, and Jackal Snipers still being deadly but much more manageable through changes to their aiming stats. Many weapons are now more powerful than in Vanilla, and AI do more damage on all difficulties globally, but AI have also had proper damage modifiers added so that they're much more fair like Combat Evolved.
The third part of Halo 2: MJOLNIR Edition. Contains Delta Halo through Quarantine Zone.
DELTA HALO: Player starts out with extra ammo for Rocket Launcher and SMG, with more ODSTs fighting alongside you. Various Jackal Snipers have been given carbines in place of Beam Rifles. Certain Elites also wield Jackal Energy Shields alongside Energy Swords... because it looks cool.
REGRET: The number of Marines that start the level with you has increased dramatically. Most of the Honor Guards defending Regret also wield swords, because the sheer number you'll be facing off against will already make the fight difficult enough without having to worry about dodging dual-wielded plasma rifles. As with the previous level, some Jackal Snipers have had their beam rifles replaced with carbines. The Prophet of Regret's gravity throne has had its collision model restored, meaning you can now lock on with weapons like you could in the OG X-Box version of Halo 2.
SACRED ICON: The player now has some Elite allies early in the level. Also, much like Ruby's mod, the player will fight against Marines at various points. Be careful on Legendary, because Marines can be lethal in groups. Regular Sentinels are now dark blue in color and fire the sentinel needler. Gold sentinels remain unchanged.
QUARANTINE ZONE: As with the previous level, the player will fight against Marines at various points in the mission. Also, certain Flood-controlled Wraiths have been replaced with Covenant-controlled Wraiths, once again inspired by Ruby's mod. You also have more Elites fighting alongside you on the final Gondola ride, as influenced by Ruby's mod. Once again, regular sentinels are dark blue and fire the sentinel needler, while gold sentinels remain unchanged.
