Der im Mai anstehende Patch zu Halo 5: Guardians (ab 5,48€ bei kaufen) wird laut Halo Waypoint (via Gamespot.com ) nicht nur am Mehrspieler-Part schrauben. Nach der Analyse vieler Spieler-Rückmeldungen, Tests und Let's-play-Videos will 343 Industries auch den Schwierigkeitsgrad der Kampagne verändern. Im Alleingang wird es zukünftig schwerer, im Koop-Modus leichter. Die Änderungen seien allerdings nur dezente Feinabstimmungen. Vor allem den Wächtern soll man neuerdings leichter ausweichen können; die Änderungen gelten auch im Kriegsgebiet-Modus des Mehrspieler-Parts. Hier eine Übersicht:

"SPECIFIC CHANGES

• Reduced two-player difficulty slightly
• Increased single-player difficulty slightly
• Made Warden attacks a little easier to dodge, particularly on lower difficulties
  • Face Beam tracks moving targets less accurately
  • Gravity Bomb has less homing
  • Melee attack has slightly less range
• Made the Warden slightly easier to kill from the front
• Reduced AI Focus Turret damage output
• Reduced AI Storm Rifle, Suppressor, and Light Rifle effectiveness
  • AI Storm Rifle: fires in shorter bursts, projectiles spread out more and move more slowly. Jackals are now less effective than Elites with the Storm Rifle
  • AI Suppressor: fires in longer bursts, projectiles have less homing. Crawlers are now less effective than Soldiers with the Suppressor
  • AI now fire shorter bursts with the Light Rifle
• Increased AI Plasma Pistol, Needler and Beam Rifle effectiveness
  • AI Plasma Pistol: slightly higher accuracy and damage
  • AI Needler: AI now fire longer bursts (i.e. can now supercombine players on Heroic and above), slightly higher damage
  • AI Beam Rifle: slightly more damage (mostly this will make it a two-shot kill instead of a three-shot kill in Heroic single player, allowing Jackal Snipers to actually kill a player from time to time)
• Added a "tackle" animation to Sword Elites – shoutout to Pat Gillette for making the sweet sword tackle animation
  • Instead of stopping to swing at a moving target they can swing on the move
• Increased Elite, Elite Officer and Soldier Officer durability
• Reduced Soldier bamf frequency
• Killing a Crawler now deals area-of-effect damage to all nearby enemies, softening them up or killing them outright
• Reduced frequency of Squad AI getting killed while in a gunner's turret in a player's vehicle
• Made being killed by an attached Plasma Grenade non-revivable, similar to lethal damage from a Binary Rifle
• Increased AI special ability chance with higher player count in co-op games, e.g. Plasma Pistol overcharge, grenade throw
• Increased AI promotion chance with player count in co-op games
  • i.e. in cooperative games you will encounter more high-ranked enemies where promotion paths exist (most noticeable with Grunts, Elites, Jackals and Crawlers)
• The first player to press the "Call for Help" now has priority, other players will have to wait their turn for a revive – shoutout to Mr. Robert Kingsley for the code fix for this.

• Removed Binary Rifles
• Swapped Sniper Rifle and Rocket Launcher weapon pads (Sniper to "Yellow Tower" / Rocket Launcher to "Green Tower")
• Suppressor moved to bottom of the Grav Lift

• SAW weapon pad modified
  • Max ammo reduced to one magazine total (no reloading)
  • Respawn time reduced from 3 min to 2 min

• Shotgun moved back to Tower One
• Plasma Pistol moved to "Mid" the small street in between "Tower" and "Pit"
