good idea let go put in IM upg parts 2.0 3.0 , it would be very good to get weapons
Make upgraded weapons farm-able in game. (slow process available for all lvls)
Have upgrades sales, reguarly and with a similar cost as the old upgraded weapons
Do not change anything about the current state of the game
A combination of option 1 and 2, which would include sales & farming the weapons
