Players control Snake through the game map and attempt to complete missions while avoiding being spotted by the enemy. The threat detection system is revamped, with the removal of the onscreen meter or gauge to indicate the player that they are in the alert/evasion/caution state as in previous games, which have instead been replaced by visual and audio representations. Snakes binoculars have also been revamped; instead of selecting the binoculars as an item, the binoculars are hot keyed to a button. The player is able to mark enemies and be aware of their locations in the iDroids holographic display.
