This rocket launcher dealt a stunning 800 damage before the 2/9 update, after which it was nerfed to 700. Soon after, the fire rate was cut in half from 4 to 2. However, it was buffed back to 800/1600/2400 damage with a 1.8 second reload around 11/5/2015.
However, it is still a relatively powerful and useful weapon, especially for early levels. It is most set back by its two-clip capacity, which cannot be alleviated with the Capacity augment.
Paired up with 25 points in Adrenaline will make the HVM MPG one of the best mobbing weapons due to near instant reloads for unlimited capacity for that duration. It also has a low movement reduction of 18% (just over half that of the T-101 and the Gebirgskanone), which makes this weapon viable for Vaccine and running from zombies while reloading.
HVM MPG is a futuristic double-barrel rocket launcher which appears to be a successor of RPG. It appears to be the least blocky weapon among HVM weapons as having curved parts.
The HVM MPG is one of the few weapons to have any other color than black, gray and white (that color being yellow).
The HVM MPG has the second-highest pierce of all rocket launchers, with the highest belonging to the Zerfallen, which is a PREM weapon.
Its description in the alpha version was simply "Double barreled".
