I am wrecking shop with that C.A.R. SMG. Running counter weight on it and the HCOG sight, and just destroying fools. I have started to figure out my gameplay style now and I am typically either going positive or at least 1:1 for my pilot to pilot KDR.
(The odd time I am still going negative, but not that often)
Just before bed I went 13 and 3 with 20-something AI kills.
The smart gun is a hassle to use but I got so sick of seeing myself get killed with it in the killcam that I decided to spend an evening learning how to use it.
I got good with it and unlocked everything, but when the shit gets thick I tend to gravitate back to my run & gun loadout with the counterweighted Carbine and stims perk.
All I want to do is play this game but the wife has decided that she wants me to suddenly spend less time on the Xbox and more time with her. She does this every time a new game comes out that I love, ususally in November with CoD in the past.
My Titan is a machine of destruction too. I call them in and let them wreck shit, and if I am in the area and not engaged in pilot killing, I will throw Arc grenades and then launch the magnetic grenades at the offending Titan with my noobtube, which racks up a lot of Titan kills when the enemy is engaged against my Titan on autopilot, his sheilds are down, and my titan is firing grenades and cluster rockets at it at the same time.
Killer game. Best shit ever.
Edited to add that I also run the "Run n Gun kit" as my tier 1 kit.
