Serious Sam has the ability to travel in space and time, so the player will visit different eras on earth and different planets.The games in the series are predominantly traditional 3D shooters, where the player has to slay many enemies and some boss monsters. The monsters usually appear in large numbers and often have somewhat unusual design. Some of the used weapons are also uncommon and there is also an "all-killing-bomb", like in the old arcade games. Serious Sam games attempt to recreate the style of old FPSs such as Duke Nukem 3D, both gameplay-wise and in their humorous overtones.
