Recently, we received the ability to upgrade our Assaulter 1s via upgrading the Assaulter 2 tree.
However, there still remains many weapons and items we can’t upgrade. This includes the Mannlicher M93 and the MP717r, although I do not have the gun so I will focus on the M93.
As we all know, the M93 was removed from the shop after the merge. However, as I stated earlier, you cannot upgrade it. My suggestion is to allow us to upgrade the weapon with no need to upgrade any squad trees.
