Well don't lose hope a lot of the newer features in updates are community request!
I made a thread asking for them (which I linked on page 1), but I haven't heard anything from 343. 😖
Bayonet assassination suggestions:Neurosurgery sounds awesome, I really hope 343 uses some of your ideas, they're awesome!
Just a Slice: Spartan A grabs Spartan B's right shoulder, turns him round and slashes him horizontally across the abdomen.
Big Needle: Imagine the Inevitability assassination, but with a bayonet.
Tip of the Spear (uses thrusters): Bayonet version of Terminal Velocity.
Can Opener: Spartan A kicks the back of Spartan B's knee, forcing him down, then Spartan A swings his gun like a battle axe to slice B's neck. (Idea by Eleventh Sniper)
Outta My Way: Spartan A shoves bayonet into Spartan B's back, then kicks him off. (Original idea by CMShankz)
Neurosurgery: Spartan A stabs Spartan B in the back of the head, then knocks him to the floor with a rifle butt to the head.
Quite the Ride: Spartan A sweeps the legs of Spartan B and, as he hits the floor, Spartan A bayonets him in the stomach.
Shoot 'em up: Spartan A grabs Spartan B's right shoulder, turns him round, stabs him in the stomach then shoots him off.
My main concern is that 343 don't know that the idea is there.
I made the "request" thread a few days ago. Unfortunately, it has "sunk to the bottom of the pile" (in terms of visibility).
I'm hoping that ske7ch has seen the link, as he would have likely been the one to put this thread in the "Featured Topics".
