The idea consists of a backpack turret, mainly being mounted with the muniton backpack for more usage

The turret can be adjusted with types of many many ammo listing from
Plasma - High damage, less range due to fast fading of enegry
Bouncy - less damage, bullets are almost like rubber
Penerating - Less damage, but armor shred's to bits under impact
Normal - Base Damage, No buffs or debuffs of kind.
Blazing - Less Damage/Lingering Damage, Flame damage basicly, but less range.

Also all of the ammo types could have their own turret model, (except for bouncy and normal they would be same)

They should also have their own refilling ammo entity's to work with!
