The title says it. It's easily the worst VS Carbine and the worst carbine in the game. The unique mechanic is detrimental as you can't get full headshot damage per shot unless you're at point-blank, where it's outclassed by Serpent and VX6. At range, Pulsar C out-does it because of the shot-splitting mechanic and high-velocity ammo. Horizon has excellent base velocity, but because of less rewarding headshots as a result of only 33/50% of your damage going to the head, you can't get short TTK at range. The unique mechanic completely guts this weapon, being marginally easier to use isn't much in a category of spray-and-pray and zero recoil headshot machines while not being nearly as rewarding.
