The Specialists is an action mod created by Filippo "Morfeo" De Luca and Lorenzo "John_Matrix" Pasini, built on by a strong willed community and the first multiplayer game ever featuring slowmotion. The standards of the First Person Shooter still apply but are augmented by an intuitive stunt system, slow motion action, hand to hand combat and an array of melee weapons, customizable firearms, particle effects and the ability to play from a third-person camera.
Just BADASS is all I can say about this mod. Although it has no major game-breaking bugs, some imbalances are to be found, but back in the day I had a blast playing it. Give it a go if you like Max Payne or *put any other memorable action movie title here*.
