Another week where this challenge shows up and you have to either swap it out or grit your teeth through a couple games of misery.
Change it and this challenge goes from misery to fun.
From ‘Kill X Spartans with the Pulse Carbine’
To ‘Break X Spartan shields with the Pulse Carbine’
I like the pulse carbine. I tell my buddies often how they should be picking it up. It’s great! But it is absolutely not meant to finish kills in PvP. Stop asking me to do that with it.
We hear you! This challenge has been updated to read “Damage an enemy Spartan with the Pulse Carbine and kill them with the Plasma Pistol.”
Hope this makes things easier for you, and happy hunting! 
Took me about 4 hours to get 3 kills with it last night (or at least the ones that tracked), most of the arena maps are a bit too tight quarters to make it effective beyond a single corridor.
It works really well on Catalyst actually. Only one I have had any success with it anyway.
Had that one last week and it was bugged. Got all 3 in one game and it only gave me 2. Proceeded to get 1 kill with it in each of my next three games and it never gave me the last kill.
It’s actually not that hard to do in a game where the connection is good and there’s no desync.
Which is pretty much never.
It’s a shame because in a clean game the pulse carbine would be extremely powerful and everyone would want to use it. As it stands, most people think it’s terrible when the weapon isn’t the problem
I never found the Carbine that difficult to use and there are definitely far worse challenges still in the game.
“Get X Amount of back smacks”, one where you usually have to go out of your way to get and more often then not are just a detriment to your team trying to pull it off.
Dude this had me dying laughing 
I take it back. Just got 6 kills in a game with this thing.
Ugh I feel that. LSS event week gave me nothing but back to back backsmack challenges.
While I still hate them, at least LSS is one where your on your own ( can’t be a burden towards your team ) and has motion tracker disabled, which is a game changer when it comes to going for backsmacks. Just got to pray you get a ton of player who just bum rush everything blindly without make sure there’s no where hiding in corners and you’ll get them…
Or camo up lol
It kinda sucked how camo and OS dropped less in LSS during alpha pack, but all the melee and back smack challenges had the same counts.
Camo was pretty necessary for three back smack challenges imo
Yea I play BTB for this. 2 out of 4 maps have plenty of Pulse Carbine spawns and it’s much easier to “snipe” an unaware target with the Pulse in BTB.
Pulse remains one of the most unintuitive weapons of Infinite, where it has a sweet spot between too near and too far where the Homing is JUST right and holding the trigger down nets you a very quick 1.5 kill.
I dont mind this challenge. The pulse carbine is very effective on mid range. Takes a little bit time, but kills with pulse carbine can be achieved, with little effort.
I hate the challenge where you have to have to be one of the top 4 in Rumble Pit.
Honestly I hate the get kills with pulse carbine challenge. Shells are too slow and people just dip before they even hit. So I have to pull a reverse uno. I use a BR to cause substantial damage then use the carbine to finish them off. Issue is like I said the shells are slow so I have to close the distance like energy sword range in order for it to do anything.
(Reverse uno being that normally you use plasma to take down shields, then use ballistics to destroy health. Here I had to do the complete opposite… it works tho)
