Little tip to save time.
0. Gold Imposing Arsenal Trophy
1. Buy the weapons until lv 4 (from the maj on we must buy the levels to mount them),
once the weapons lv 4 mount them while playing to unlock the lvl 5 but do not buy it, made its for all the weapons.
2. Make a backup of your game on a USB key and buy all the weapons lvl 5.
3.Once the trophy has been obtained, quit the game and make a copy save of your USB key to recover your money.
4. Handyman Trophy
It will save you a lot of hours of unnecessary farming.
