Let them fight...

Okay, so the predator has killed all 3 of your team mates.
How do you die?

In my experience pretty much the following:

  1. Combistick / Wristblade-flurry (typically in the same rush as which killed the other FT members)
  2. Assortment of any other goodies the pred has
    All initiated while cloaked. Yawn.

Just a thought but how about the following:

When it comes down to a 1v1 situation a challenge option activates within a certain radius.
Either FT of pred can initiate the request. Put it in the chat wheel (grayed out until 1v1 situation).

If the opposing player accepts queue short cut-scene.

Predator drops his mask (which many have called for), pops blades. Roars.
FT drops gun, pulls knife (gestures like Billy / yells like torch-bearing Dutch).
Back to in-game.
Weapon switching disables in this mode.

Then we proceed to having ourselves a good old knife fight…

or

We could just go at it like savages with guns and casters as usual if one party is not up for it.
I believe the correct term is Gallus gallus domesticus

Not going to advise putting a double bounty on who-ever ends up on the ground to prevent pvt match farming for V or XP.

With the parry system a knife fight just wouldn’t work well imo opinion unless the pred literally just ran circles around ft and slashed
