Phew, finally completed the game on Crushing difficulty. Took me longer than expected but with my limited time to play, I think I did ok. Is it just me or is the crushing setting getting easier with each game? Maybe that or I'm just so used to the mechanics, I dunno. But I remember UC 1 being like insanely difficult on the hardest setting.
For this playthrough I enabled two cheats, the weapons perk and the unlimited ammo perk. On each encounter I mainly used the Barok 44--a great weapon. For the most part it got a kill with one shot. And for a rifle I used the M14 custom sniper rifle. Very effective. Basically another one-shot to kill gun that is excellent on the hard difficulty.
I was able to get all the remaining trophies minus two as expected. The 70% shot accuracy trophy and the speedrun trophy. I'm fixing to do one more playthrough to nab both those. I'm gonna use the Explorer setting since both those trophies require lots of speed and quick accuracy to get through the game. There's too much time wasted on encounters in the harder settings imo.
I have yet to play the multiplayer on UC4. Is it good? Again, I have a limited amount of time to play the game so I'm thinking I won't be able to hop into the online stuff until after my next story mode sessions are done.
