''Rez'' is a [[video game]] that combines mechanics from the [[music video game|music game]] genre and [[rail shooter]]s like ''[[Panzer Dragoon]]''.<ref name="NGrez"/> Players take the role of a hacker infiltrating a malfunctioning [[artificial intelligence]] and fighting off [[Computer virus|viruses]] and corrupted security programs.<ref name="RetroRez"/> Destroying data nodes in each level raises the "layer level" to a maximum number of 10. Raising a layer level changes the background music, layout, and enemies of a level.<ref name="RezGameplay"/> There are five levels, dubbed Areas, although at the start only four can be accessed.{{sfn|Sega|2002|p=10-11}} Achieving 100% leveling score for the first four areas of the game unlocks Area 5.<ref name="RezGameplay"/>

The player character can assume six forms at different power levels, with a seventh unlocked for Area 5.{{sfn|Sega|2002|p=12}}{{sfn|Infinite|2017|p=45–49}} The player starts the game by default at Level 01. Upon being damaged, the player devolves into a previous form. The lowest possible is Level 00, and if hit again in this state the [[Game over|game ends]].{{sfn|Sega|2002|p=12}} The player raises their level using Progress Nodes, which appear after a certain number of enemies are destroyed. There are singular Progress Nodes and X3 Progress Nodes that fill three bars on the level meter. The player can also collect up to four Overdrive Nodes, which fill a meter and trigger automatic screen-clearing attacks.{{sfn|Sega|2002|p=13}}

During gameplay, the player runs through a level on rails and manually aims a lock-on missile launcher at up to eight targets.<ref name="GameSpotPS2review"/><ref name="IGNPS2review"/> As the player shoots down enemies, the impact automatically syncs with the background track to create additional musical layers within each level.<ref name="RetroRez"/><ref name="GameSpotPS2review"/> The shots can be fed back to the player through controller vibration feedback.<ref name="RezGameplay"/><ref name="RezVibrations"/> Each Area ends in a [[Boss (video games)|boss]] fight.<ref name="RezGameplay"/> Bosses scale in [[Difficulty level|difficulty]] depending on the number of enemies killed in the previous layers.<ref name="RetroRez"/>

Progress through the game unlocks additional areas and modes including an enemy-free exploration mode, [[Score (game)|score]] attack, and boss rush.<ref name="RezGameplay"/>{{sfn|Sega|2002|p=16}} There is also a mode where all five areas are played back to back with raised difficulty.<ref name="RezGameplay"/> Each area's completion is scored by Analyzation (data nodes accessed), Shot Down (enemies destroyed) and Support Item (support nodes collected).{{sfn|Sega|2002|p=8-9}}
