I don't recall seeing anything recently about it so I assume it couldn't have happened recently, but has the hydra ever gotten a buff? I use to try to use them and couldn't really pick up kills with it, so I rarely grab one with the intention of using it on people. In the above match though I grabbed our hydra and stealth after both enemy vehicles were down and half the enemy team was assaulting out flag, so I started letting off shots. I picked up six kills pretty quickly with it before running out of ammo and was surprised to find that I was killing each person with with two direct shots (no splash damage), because I could have sworn it took three. Has it always been two-to-kill and I am just crazy?
I think it has always been 2 direct missiles to kill? Or at least, for a while.
When they buffed it in May:
Hydra Launcher: Default
Reduced recoil in hip fire
Increased inner AOE radius from 0.4 to 0.8
Increased impact damage to make it more effective against vehicles (still two rockets to kill Spartan)
Hydra Launcher: Typhon
Enabled multi lock on for up to 3 targets
Increased impact damage (still two rockets to kill Spartan)
