I'm just being stupid and having fun with the idea of someone in the Halo storyline hacking the Warzone Simulator to add a gravity hammer that's a baseball bat themed on Babe Ruth. The idea is that if you hold down the trigger your Spartan points the bat forward (calling a homerun to center field) which powers up the hammer and then it swings around like 360 or something so it has increased range and a silly amount of knockback (works on vehicles), but otherwise normal power. Maybe the power could even be weakened a little. It'd be kinda funny if enemies only lost their shields but were knocked out of reach and you had trouble getting a kill. Side note: Isn't there something sinister about how the war simulator pits human vs human? WHAT ARE THEY PLANNING??!
For a REQ unlock you could get the Mark V Armor with the original NY pinstripes uniform design on it, and a longer bill on the helmet to make it look like a baseball cap XD
If this were a thing id like a unique assassination with it, like tripping the guy to his knees then swinging at the head like a t-ball
