1. The Chaingunner Zombie (AKA Zombie Chaingunner or Chaingun Commando) is the most powerful zombie enemy in Hunter's Moon. The Chaingunner Zombie differs a lot in appearance from the other zombies. For one, he is barechested, wearing only a helmet and trousers. Moreover, he is more muscular, having been augmented by the demonic forces for their own use - deploying the Chaingun Commando.
2. The chaingun's mobile turret mod is perfect against bosses who need a lot of ammo. It is important to note that the chaingun shares ammo with the heavy canon, so jump between them wisely.
3. I liked the Shield mod for the Chaingun more than the Turret Mode. The Turret has insane damage, and it's not THAT bad on bullet use overall. But the lowered mobility makes you an easy target for every projectile. It's best used to just tear up the Super Heavy demons but aside from that the regular Chaingun does the job just as well.

The Chaingun’s alternate fire modes are; Mobile Turret and Energy Shield. Mobile Turret transforms the Chaingun into a mobile turret that can overheat and stall. Energy Shield activates a shield that absorbs incoming damage for a while. Fully upgrading Mobile Turret means that it no longer overheats or stalls.

The chaingun is a rapid fire bullet weapon. It is dropped by chaingunners and uses clips for ammo.
