Viva Caligula

Viva Caligula! is an action game in which the player assumes the role of the mad emperor Caligula in ancient Rome. He has decided to rid the city of its citizens, massacring the lot of them before heading to the orgy.
Caligula has to gather all 26 weapons he can use, before he can enter the palace. Among these are blades, axes, crossbows and even more unusual weapons, such as wasp hives or lions. Each of these weapons can be used with it's corresponding letter on the keyboard (such as S for Sword, A for axe), while Caligula is controlled with the arrow keys.
Walking through the seven hills (levels) of Rome, Caligula will face ordinary citizens, prostitutes, beggars, legionnaires and gladiators. After killing a certain amount of citizens to fill his rage meter, Caligula enters rampage mode, in which every blow he throws instantly kills his victim in a very brutal way. Also, the game has the option of allowing the player to shout into a microphone, increasing Caligula's rage meter.
