It's a puzzle game in which players move Nathan Drake around a maze, and if completed using a set amount of moves, keys will be unlocked. Keys are used to unlock loot boxes which contain skins, alternative clothing and one use boosters usable in Uncharted 4's multiplayer.
Sully is also included in the game and will send notifications to the player when there are more treasure chests to unlock. Some include really nice loot such as gear, heavy weapons, Mysticals and more.
There are a few microtransactions in the game, these are optional, as earned orbs can be traded for coins to spend on vanity items. If you really want to spend money though, 20 orbs can be purchased for £1.49 and the price goes up with the amount of orbs purchased.
If you want to know the location of all the treasures in the game, you can buy a Treasure Map for 79p. You can see some of the microtransactions below.
