Atomic Heart

A first-person perspective shows a player wielding a gun, firing at various enemies in different environments including an outdoor area with debris, a dark industrial space with glowing red lights, a dimly lit room with metal structures, a dark outdoor area with glowing green creatures, and a confined space with a large blue energy effect. The player moves through these settings, engaging in combat, with the gun firing and enemies reacting to being hit, resulting in visual effects like sparks, blood, and explosions.
