Shadow Complex is a critically acclaimed 2D action-adventure game developed by Chair Entertainment and published by Epic Games in 2009. Initially released as part of the Xbox Live Arcade lineup, it later made its way to other platforms like PlayStation 3, PC, and mobile devices.

Players can engage in both ranged and melee combat, with the latter being particularly visceral and rewarding. The game also features a cover system that adds an additional layer of strategy to firefights. Despite its retro-inspired visuals, Shadow Complex boasts impressive graphics and animations for its time, with detailed environments and smooth character movements. The game's art style perfectly captures the spy-thriller vibe, complementing the game's narrative premise. Speaking of the narrative, Shadow Complex presents a compelling storyline that unfolds gradually as players progress through the complex. The plot revolves around a conspiracy involving a domestic militia group and a secret government organization, offering an engaging blend of action and intrigue. Overall, Shadow Complex is a standout title that pays homage to classic side-scrollers while introducing modern gameplay mechanics, impressive production values, and an engaging narrative.
