📋 About This Mod

Halo Reach: Prometheus is an overhaul of Halo Reach built upon Reach Evolved (from TheVengefulVadam) that adds over 20 new guns, new vehicles, enemies, and allies. Every single fight has been edited for larger engagements and more complex engagements. All AI for friendlies and enemies is reworked. Grunts behave differently in swarms and alone, jackals phalanx and flank with quick birdlike movements, skirmishers leap around the map with rifles, Brutes charge the player aggressively, and Elites constantly dodge and outflank. Player stats changed for movement, health, shields, and armor abilities to make the player faster, stronger, and more lethal than ever to combat the greatly enlarged enemy groups and greatly improved AI. NOBLE Team AI is also edited to be more effective, and your allies for the more UNSC focused missions have been reworked across the board to make every fight larger or more intense. This mod is released alongside a separate sister mod, a Reshade preset called Torpedo, which brightens and enhances the existing Reach colors, along with the skya and fogg changes in Prometheus, to make every level feel unique and vibrant.

This mod is a work in progress.

Changes in 0. 4 (Scroll down for previous release changes):

  • []Major difficulty rebalance. All Non-Legendary difficulties adjusted. Players newer to Prometheus will have a much better time adjusting to the new AI and weaponry on Easy, Normal, and Heroic. Lots of changes that include accuracy, burst duration and separation, and so on. Legendary will stay at the same challenge that Prometheus v0. 3 released with. Brute redesign. Brutes now use new armor permutation setups, ranging from Recruit, Minor, Major, Alpha. These will dynamically adjust depending on difficulty setting, campaign level, encounter, and so on. Recruits have no power armor, but Minor and Major will have blue and red power armor with Gold Shields that do not regenerate, similar to Halo 3 Brute Power Armor. Majors (in red armor) will also exhibit more careful AI than Minors. Brute Alphas instead use new black and red armor, with Blue Shields that regenerate much like Elites. They have vastly improved AI and will constantly flank the player and root them out with grenades and other new tools. The original Captain, Stalker, and Chieftain ranks will spawn separately from difficulty as set encounters, but the Captains will have non-regenerating Gold Shields.

    []New Vehicles. The Apparition from Reach Evolved is now joined by a Spectre-style Revenant as a vehicle the covenant will employ against you. There's a new Harbinger Banshee to play around with in a later campaign level, along with another surprise vehicle on that same level. Plasma Turrets now have  energy shields similar to Jackal shields which force you to change your strategies against them.

    [*]New Weapons and Weapon Rebalance. Not only have all weapons been reba
