Blast all the bad guys by your self or 2 people can join together to defeat the enemies. The game is very realistic and the guns actually recoil every time you shoot! Just like in the original, the game takes the players through different levels. They must blast all the bad guys in each area before time runs out. Fortunately there is a special pedal, which you step on to pop out of hiding so you can fire back, then release to go into hiding (and to reload your gun.) There are several levels of game play and a subwoofer that really adds to the excitement!
