Sir Arthur has gotten old... too old. He has lost everything he had and loved, and with nothing more to lose he leaves for Samarnath, an evil subterranean kingdom (which no knight has ever returned alive) in search of treasures, adventures and the most important: five magical orbs that together provide: the Eternal youth. Thanks to its progressive difficulty curve, and with a path divided into “worlds” of 5 levels each one, Eternum Ex is challenging, addictive and an ode to the nostalgia of the golden age of arcade games.
