Gotham Knights is an action role-playing game set in an open world Gotham City.[1] The game features four playable characters: Nightwing, Batgirl, Robin, and Red Hood. Each character has their own unique playstyle and abilities,[2] such as Robin being able to teleport via the Justice League's satellite.[3] Players can level up their characters, but enemies will be automatically leveled up as well.[4] They can also use vehicles such as the Batcycle to explore the city.[5] During the daytime, players will occupy the Belfry, which acts as the team's base of operations and allows players to switch characters and prepare for the next mission by managing progression, and upon leaving the Belfry, the game will fast forward to the nighttime.[6]
While the narrative campaign can be played solo, the game also features a two-player cooperative multiplayer mode, wherein the second player can drop in and out at any time without affecting the other one.[7] A separate four-player cooperative mode named "Heroic Assault" was introduced in November 2022. In this mode, players battle enemies across 30 levels in an arena-like environment while completing various objectives.[8]
