Turret Bases will come in 5 tiers. The segregation between them will be made a bit more linear.
Tier 1 will only have Ammo slots, and needs to be charged via rightclicking it with a lever item (not placed anymore)
Tier 2 will have 1 upgrade slot.
TIer 3 will have 1 upgrade slots and 1 addon slot.
Tier 4 will have 2 upgrade and 1 addon slots and be controllable by Computers (which mods shall be decided later) automatically.
Tier 5 will have 2 upgrade and 2 addon slots and be controllable by Computers (which mods shall be decided later) automatically.
Additionally Tier 5 Bases will be used in the future as the foundation for bigger weaponry.
