Halo 2: Anniversary cut content
From Halopedia, the Halo wiki
the release of Halo 2: Anniversary Multiplayer has seen a fair number of cut, unused, and carried over content from the title hidden away in its files, many of which have never seen a release to any capacity. Below is all available information on that content.
files exist for the Halo 4 power up of the same name, however picking it up automatically applies the Speed Boost effect.
Functions near identical to it's Halo 4 usage, albeit lacking an overheat indicator. it still uses it's lower detail textures from Halo 4
while almost completely functional, the textures for the Missle Pod Turret appear to still be a lower resolution carry over from Halo 4.
Halo 4 Energy Sword
Visually Identical to the Halo 4 Energy Sword, appears completely functional using original Halo 4 Animations and SFX.
Halo 4 Assault Rifle
Uses the same animations as the Halo 4 MA5D, causing the weapon to become misaligned to Elite animations. it has a broken audio loop causing the weapon firing SFX to stack indefinitely.
Visually identical to it's Halo 4 Counterpart. Set up much like the Armor ability from the campaign component of H2A while also sharing the radar jammer effect from Halo 4, it lacks the needed stats to reset the charge to 0 when canceled.
an assorted number of left over elements exist in the files, though none of it appears completely functional
Chief (Halo 4)
3 untextured versions exist, the other two being internally named "keep_for_sp" and "strip_for_mp" respectively. possibly intended for early testing and development purposes.
Both Male and Female variants exist with their associated techsuits. oddly the Male techsuit is the only textured asset, still using it's original Halo 4 textures.
Files exist alluding to a Flood variant of Elite being planned much like the Spartans, although the concept was ultimately dropped as the biped remains unchanged.
