Yeah this game is absolutely stunning. Sometimes you run through rooms with insane detail on wall carvings/murals, where you only stay for 5 seconds. The dedication of ND is remarkable.
Also, some important info gathered for trophy hunters about the finicky and vague 'Way of the Warrior' trophy.
- Update to the latest patch because there's a bug that makes a grenade close to you count as a weapon fired
- Don't touch any button related to guns, don't even mark enemies to be sure. This from the prologue to the start of ch5. You can make a manual save before the first encounter in ch3 to save time.
- Start a new game without carrying over your stats. I had to look for this on the official ND support pages: "Additionally, you have to start a New Game and opt to NOT carry stats over when prompted whenever you attempt this Trophy."
I'm going to do a 4th try after work, hopefully it finally unlocks because I never reset my stats. All the other trophies are easy but this one is hell somehow. Just because of the unclear and very specific requirements.
It's a standalone adventure like all the other Uncharteds, but it is definitely related to Uncharted 4. I would still advise you to play it because it's one of the best entries in the series, but it's loosely tied to U4 in particular.
