In game clould be implemented a “no weapon” situation…especially in close conflict, melee could be replace by fights, like as the fighting game… with combo for the enemy disarmament and damage inflict…
or, more simple, create animation like as the assassintaion, in front also…but combo feature could be more interesting…
like as the Jason Bourne films… 
no thanks. I don´t want halo turning into some mortal combat.
Would be cool for customs, but I don’t think it would work in standard multiplayer.

Should be in Customs/Campaign/SpOps
Perhaps a finishing move/assassination type thing, but I really don’t see it working all that well in general Halo.
Or just have a “None” selection for both Primary and Secondary weapons in the Game Options.
