Ah, the no loading screen mod is back (was a version in Just Cause 2 for Black Market). I've not checked the mods for this recently, but are there multiple sites or is it just the one. The last time I did check, there were the inevitable mods that removed cooldowns for the black market vehicles and unlocked hidden items in the black market.
I hope there's a mod which adjusts the ratings for the challenges to make getting gears easier. While it's silly that I'd rather work for my unlocks, I will admit the current system is stupid, they should just give us the gears for completing a challenge once or something. I miss collecting things from Just Cause 2, while it wasn't everyone's cup of tea, one could just get a mod to make the upgrades free (not require collectibles) in that game.
