Totally got 2-3 kills today with the plasma rifle, and I got at least one kill with the spiker. Totally the most difficult weapon to get a kill with is the spiker. I am a total hardcore pro o.0!
I have 38 kills with the Spiker in Matchmaking… most fun I ever had. But I wouldn’t call it “pro”

EDIT:
Also 18 Plasma rifle/ 49 Plasma Repeater kills. Pretty easy to do, especially if you use the plasma pistol to pepper off their shields. Not hard, not fun and certainly not “pro”
and lol, I have 67 Plasma Pistol kills in matchmaking. I love HaloTracker
I have 114 kills with the Spiker, which is also my best K/D ratio.
Also lead to one of my most memorable kills where upon killing someone a teammate screamed, “He got a kill with the Spiker!?!?”.
Unfortunately it also lead to one kill that saddened me about the community on Halo, where upon shooting at an enemy he screamed, “What the hell is that weapon!?!?”.
I need to actually try use the Spiker in matchmaking

IKR? They act like they never seen the weapon before and often make accusations similar too “you hack!”
That’s kind of funny that someone did not know what the spiker gun was.
Cool, cool.
