The Experimental Sample is a Dying Light 1 level that focuses primarily on parkour, with combat serving as a secondary but meaningful element. The player must sprint through a city engulfed in flames, collect four large crates containing Experimental Samples, and ultimately defeat the boss to complete the level. The level also offers optional side-exploration areas—if players manage to overcome environmental hazards such as fire and reach these hidden spots, they can earn additional rewards. Throughout the level, players can engage enemies using multiple combat methods, including luring them into car traps and detonating the car batteries, baiting them toward explosive oil barrels and igniting them, or kicking enemies into spike traps to instantly eliminate them.
