Some other unrelated suggestions I've been thinking as of late
- Seeger replenishes his coffee stock whenever you present him with a Lemurian folding screen computer
- Upon negotiation/razing, Grimm moves the brewing machine to his office, and offers some each time you give reports on your tasks
- candy/protein bar food item that increases movement points.
- now for something more complex; Upgrading of unique armor.
i was thinking it like this, unique armors come in categories available as craftable options (tactical vest, leather armor, metal (or metal-ish) armor), the former made with common crafting components like bolts of cloth and ballistic panels, so my suggestion is that common crafting components could be used to boost the stats of unique armors, in a balanced and relevant way for each type.
For example; if a unique tactical vest doesnt have an overcoat, let only panels be made available to boost its protective capabilities, (with inferior scaling compared to ordinary crafted tactical vests, maybe), a heavy armor that could reasonably be disassembled and reinforced with metal plates, or if a leather armor could be padded.
