Ever since the invention of online games some niches have become popular because of the violence, epic themes and multi level environment. Movies such as Troy and the 300 (Spartans) give epic games more of an edge, these applications are based on such times which are remembered as the most bloody and dangerous times in human history.

Several version of these epic games have been released and tested by many action-fighting game enthusiasts, cartoon network came up with a good, bloody game which takes place in Rome during the times of the infamous emperor Caligula who killed people for pleasure and thought of himself as a God. Those who have tried this entertaining yet gory game can tell that the massacre never ends, the actual plot revolves around the killing sprees Caligula use to take in order to achieve the things he wanted. In order to advance from level to level there are many peasants, guards, merchants who he must kill.

A famous game in the same category as "Viva Caligula" is called the "Age of War", this one is not as bloody as Caligula's but it is quite amusing, in order to advance from age to age you must protect your fort from those who invade it by building several levels of protection around it, there is one special move you can use only once which varies from age to age, during the prehistoric age you are able to use a meteor rain in order to completely destroy the invaders. The ages and wars start at a very basic level and escalate into more interesting times such as the time of gladiators and getting all the way to the contemporary times were you will defend your base against commandos using missiles.

A third interesting game which has gained popularity because it is similar to "Viva Caligula" is called "Achilles" in this game you have to defeat several gladiators using nothing but spears, shields and swords. The options in this online application lets you turn the blood on and off, just in case you just want to defeat your enemies without watching them bleed. The controls in all three games described are quite simple, the arrows in your keyboard can be used to mobilize your figure and numbers/letters can be used to attack/defend.

Because of their violent nature it is recommended these free online games be played by a somewhat mature audience 15+, in other words they are definitively not for children by for older teenagers and young adults they can be as much fun as any other fighting/action game played in consoles.
