Because the spartan IV’s are two modles ahead of the chief in tech, does that mean they’ll play diffrent in multiplayer than campaign? e.g higher jumps more shields etc.
Probaly not but just a tought that struck me remember the chief is only a Spartan II so it migh be possible.
Hope not.
IV’s are not ‘better’ that II’s in any way. II’s had more extreme training and biologically is the only place they could be on par with them.
So no, no difference in gameplay

from the bulletin
Well considering that the Spartan IIs were genetically some of the best of the best and trained from a very young age and the Spartan IVs are volunteers who likely received less training and are most certainly of lesser stock.
At best they’re likely to be on-par with Spartan IIs if the enhancements have advanced so far as to allow that.
