As for permadeath, it’s just what it sounds like. At its most aggressive, a single death ends your entire game. The truly insane can combine this with Grounded mode and see how far they can make it, but there are also more forgiving options. Permadeath can be set to “one day,” which means a death sends you back to the beginning of the day your character was playing through. Getting through an entire day without dying is still pretty challenging, so there’s also a “per chapter” permadeath. Given each day has about a half-dozen chapters, that should be a bit more manageable.
Given the challenge of these modes, Naughty Dog is adding two new trophies to the game: one for beating it with any permadeath mode enabled, and one for beating it on Grounded difficulty. But if you want to get a platinum trophy for the game, fear not — these new trophies are a separate challenge.
Naughty Dog also made some changes for those not obsessed with challenge, as well. In keeping with the game’s huge variety of accessibility options, new bonus modes let you play the game with unlimited ammo and / or unlimited craftable supplies. Naughty Dog likens them to cheat codes, but really it’s just another way to make the game more playable for a wider audience. It’ll also be a good time for anyone who has wanted to go in guns blazing, supplies be damned — maybe they should have called it “Uncharted mode.”
The list of modifiers Naughty Dog added is extensive and includes far more than just unlimited supplies, though. There are slow-motion and bullet-speed modifiers, various audio filters, an option to disable listen mode entirely (or set to to infinite distance) and a “mirror world” feature that we can only assume turns everything in the game backwards.
In a more frivolous change, there are “nearly 30” new graphics rendering modes, which change the way the game looks. Above is a shot of how it looks in 8-bit mode, though most of the other new modes are less dramatic. You can even change the sound to 8-bit or 4-bit audio, which should be a real trip. All in all, it’s quite the extensive update that should breathe new life into the game for those who’ve already finished it a few times.
