Serious Sam II delivers a boss fight at the end of each world, culminating in the conclusion of the game. While each boss is impressive in its own way, the conclusion of the game is simply astonishing, and will certainly go down as one of the greatest boss battles of all time. As the last level contains approximately 1,300 enemies, the entire level could be considered a boss match, and if the game hasn't already led to the consistent use of the Quick Save and Quick Load buttons, they will quickly become your best friends. Although the conclusion of Serious Sam II is one of the most challenging and intense fights ever, it is also one of the most rewarding experiences in gaming
