I keep seeing this around and I don't know its designation or seen anything else about it. Basically a heavy firing 2 shots, only 2, in very quick succession. Same speed as a basalisk or prowler. It can't be a visual bug as both rockets appear to do damage. The rockets don't have to follow the exact same trajectory (I'm assuming it just depends on how quickly you can 'Re-aim' the rocket. I've never experienced it accidentally while playing as a heavy. I've seen multiple people of all different factions use it In short I just wanted to announce it and see if anybody else has seen it and if it is a fast reload glitch exploit or something.
its a glitch. They're firing 2 rockets in 2 different directions because of the recoil of the gun. I'm not sure about both doing damage, I've never actually seen them both hit a target.
I've seen this happen quite a few times as well - there are definitely players shooting two rockets at the same time.
I have seen the double rocket a few times, once i had a heavy fire x4 rockets at me as well under a second. Not sure if the x4 was some sort of strange lag or visual bug as i never took much damage from it. That said i ran into a more serious bug flying my liberator a few hours ago, after having landed on the repair platform where me and my gunner repaired said liberator and got in the plane and flew off. I noticed that the plane was still acting like it was being repaired by two people and having its ammo refilled non-stop. Thus the Immortal super liberator was born, unlimited ammo and flying around with x2 engie repair auto regen. I have not been able to replicate said bug however so my guess is that it was some sort of desync or something.
