Are you kidding me? It doesn't take a rocket scientist to realize that 343 are going to ruin Halo 4.
-Armor Abilities Return
-They copied X-Ray Vision from the Blacklight games, however, it will be unbalanced in H4 solely because there will be no point in using anything else.
-Spartan Ops = Spec Ops
-Spartan Points = CoD Points
-Sprinting is a default function
-THERE IS STOPPING POWER THAT NOT ONLY SLOWS YOU FROM RUNNING, BUT ALSO STOPS YOU FROM RUNNING AWAY
-Armor now grants stat benefits
This is why every MP game gets ruined, because people like you can't see the problems early, or you just bend over and take it.
