Uncharted 4: A Thief's End includes a suite of unlockable renderers and modifiers that allow you to turn the game into an absolute circus. You can purchase them with Unlock Points, a currency you'll earn while playing through the campaign, and then activate them at any time through the game's Bonuses menu. What kind of modifiers are we talking? Well, if you've ever wanted to turn Uncharted into a cel-shaded bullet-time shooter, or an anti-gravity rainbow quest, then you're in luck.
You can watch a walkthrough of all the modifiers and renderers above.
