Knights Onrush is a deceptive game. Its deceptively simple â€“ defend your castle from waves of enemies trying to storm your gate. So in some ways, itâ€™s your typical tower defense game. But at the same time, you are far more involved in the immediate defense of your castle in Knights Onrush than in similar games. Itâ€™s not just relegated to your placing defenses and letting them do their work â€“ you have to actively deploy those defenses yourself. And thatâ€™s only one of the differences this game presents.
