I would love more physical close-quarters combat in Forefront. Since we can already grab dead players, it would be awesome if we could grab living enemies too, with some kind of counter or escape mechanic for balance.
Adding a combat knife alongside this would make close-range encounters feel much more physical and uniquely VR. Being able to grab an enemy, struggle with them, shove them away, or use a knife at very close range would add another way to fight besides shooting.
I think Forefront is at its best when the sandbox gives players multiple ways to handle a situation, and physical interaction could create a lot of hilarious and unpredictable Battlefield-style moments.
