Contrary to all the other weapons we tried and were OP, specially the Longhorn and MARS as focus commented, The Lk carbine was under powered. I used it several times without a single kill, also seems the suppressor didn't do anything. I think the button for changing the modes shall be relocated. I mean, The secondary to turn the laser on/off, the "K" for the suppressor and "M" for the Lamp. And by the way the iron sights looked incredible, but you did not have less recoil or advantage... from the hip was more accurate. Also the sounds were great. It was love at first sound... but unfortunately, was like one of those small motorbikes you hear 2 km away and passes 15km/h in front of you....
I had a headache yesterday from the stupid MARS pulses....Maybe they will give us epilepsy in reality if you increment the frequency

and everyone abusing their power....What about the pulses to heal instead of hurt? what about them not to light the complete map, their noise is disturbing.
Also made rampage twice with the longhorn, was better than a shotgun. Shoot with the secondary to a crowd and Multikill, and if you miss it bounces... You can even shoot through corners because it bounces in the walls... it is too OP.. and by the way, no way to thaw, because you just need to hit the frozen guy and the explosion covers all around...any shot is a kill with this weapon.
