CounterSide frames its story as an urban graphic-novel RPG set in a world where conflict persists between Counters and Corrupted Objects after an Administration Failure. Its stated aim is a journey to save Reality, giving the game a science-fiction noir premise with an urban-fantasy cast. The story is organized into a Mainstream, Counter Case, and Substream, with the latter two described as ways to develop individual characters’ appeal.
Combat centers on animated 2D line battles. Players lead squads and use strategy to pursue victory, while character motions and skill cut-ins add visual emphasis to encounters. The game’s illustrated cast is presented with Live2D-quality artwork and Korean and Japanese voices; composed background music is also intended to reinforce the atmosphere of different story situations. Together, these details point to a blend of squad-based tactical battles and character-focused storytelling rather than a purely narrative experience.
Steam lists CounterSide as both single-player and multiplayer, with PvP and online PvP among its categories. Its free-to-play classification and in-app purchases are also part of the store listing, while the central identity remains its illustrated ensemble, noir-tinged setting, and squad-led battles.
