How do i unlock new weapons

[Noah fp]

Ive bought all the available ones

[Seamus]

Kill bosses or find them on earth.

[CptnSpandex]

there are only a couple you can find the rest come from defeating bosses, some drop 2 different ones depending on how you defeat them.

[Hod and vampire co]

you'll get the majority of your weapons from boss kills some require special attacks like attacking a tail or keeping a npc alive during a horde attack stuff like that
