Description:

Oh, another one of those "Rebalance" mods. This mod does not add any and everything from every Halo game. Instead it focuses on "improving" (in my opinion of course), the base game. Meant to be played on Heroic.

Weapons:

-More weapons are actually useful

-AA Wraith appears as a normal enemy
-The Ark
-AA Wraiths appear as a normal enemy

Bugs:

-The flyable Pelicans on The Covenant were meant to be an Easter Egg but I have not set them up for that. Use Melee Button to fire rockets endlessly.
