Extermination is a wonderful survival horror game set within the icy walls of an abandoned Arctic research center. The story centers on Dennis Riley, an experienced Special Forces Marine who, having received an urgent SOS call, sets off with his comrade Roger Grigman on a terrible journey. Their mission takes a sinister turn when they stumble upon a horrific bacterial infection that has grotesquely transformed the once human staff into nightmarish creatures.

The central place in the gameplay of Extermination is occupied by a unique infection system, which is intricately intertwined with the health and capabilities of the player. The looming threat of bacterial infection requires strategic management, forcing gamers to navigate the ever-present risk of infection. To counter the infectious danger, specialized beds have been introduced into the title, allowing users to carry out critical self-medication, which intensifies the exciting struggle for survival.

An additional advantage of the gameplay is the ability to customize the arsenal of gamers to their liking. Weapon customizations allow gamers to add various accessories to their weapons: sights that increase shooting accuracy, grips that improve control, and even launchers that increase the firepower of the weapon. This gives the game tactical depth, allowing users to adapt to changing conditions arising from the relentless onslaught of mutated opponents.
