Frank O'connor confirmed that Armor Abilities would not be making a return and that "Spartan Abilities" does not mean Armor Abilities but they are feature like being able to hijack vehicles.
"Not thrilled that armor abilities seem to be making a return."
"They aren't. The wording is confusing but it means. "features". Using h2 as an example, new features would have been dual wielding and boarding."
