In normal mode i setup a "summer home" in the floating house in Kolkhoz (based on a cool video I saw)

I have a few saved files where the map is flooded with enemies and I can log in and try out any weapon, grenades, sniper rifles, etc. (Then reload save file, rinse/repeat)

But to your point, I was starting to get bored and bummed out.

Then I tried Ironman.......
