Each Halo of the trilogy has featured at least 1 large, naturally occurring or convenient AI collection. The Great Journey Johnson clones and The Covenant marine island don’t count since they’re less practical.
CE: AotCR Twin Bridges, 3 other megabattles
H2: Great Journey Elite Army, Outskirts 28 Ultra Elite IWHBYD fight
My highest numbers in H2:
-20 Spec Ops Elites, 20 Councilors, Johnson, Keyes, Tartarus (Great Journey)
-62 Councilors, Rtas Vadum, 2 Spec Ops Elites, Johnson, Scarab Johnson, 2 marines, 4 Hunters, Keyes, Tartarus (Great Journey)
Done on H2 Vista, there was no lag at all, only particle loss. On the other hand, I’ve only played H2 Vista on lowest settings so that might explain it’s absence.
H3: The Storm AA Gun Megabattle, The Covenant Hornet Army, Sierra 117 dam battle
My highest numbers in H3:
-56 Covies (The Storm): additional 4 warehouse Brutes
-28 Hornets (The Covenant)
-40 AI (The Covenant): 19 Brutes, 3 Grunts, 14 marines, Arbiter, 7 Elites, 2 Hornet pilots
-33 Grunts (Sierra 117)
In H3, there was only lag with the first 2 which made me suspect scripting is the reason why such a large AI collection is not feasible by default.
Imo, such large AI numbers should at least be encouraged if they aren’t naturally occurring or convenient.
In H3, I had to go through a hell lot of work to get AI. It wasn’t as simple as it was in CE or H2. The one with the marines vs. Brutes cost me my sanity and took me days to successfully complete.
