Take on the persona of the infamous Emperor Caligula and slaughter your way through Roman citizens, guards, skeletons and prostitutes with up to twenty six collectible weapons.

This is not my type of game but the subject, Ancient Rome and Caligula, that’s my interest 
The game’s artwork is good. Looking funny in contrast of the game’s main objection: Slaughter everyone. Click here to play the game. Anyways…
I was a teenager when I met Caligula for the first time. My closest friend has a bad quality VHS tape copy which he took from his grandpa’s secret video collection. The movie was a Penthouse production: Caligula. Directed by Tinto Brass. Screenplay by Gore Vidal. Produced by the owner of the adult magazine: Bob Guccione. Malcom McDowell and Helen Mirren starred. At that times I didn’t care about these movie producing details. The movie was most perverted film I’ve ever seen to that day. Understanding the Caligula, pictured in the film was so impossible but I’ve seen it. I couldn’t stop myself. Harvesting the human heads with some strange vehicles or wound someone and then pee on it or buttering the fist and inserting it to someone’s behind, these are all clear images coming through perverted realization of the movie which pop up in my head when I see the word Caligula. But, that’s not all…
Years later well known HBO series came up: The Rome. After I watch this amazing production from DVD, episode after episode, without take a break, I wondered what happened then? Then, I found a copy of Robert Graves book, “I Claudius” in my library. I buy books in bulk without thinking when I read it. It’s a method which works good for me. If I feel that a book worth to buy, I buy it. Apparently someday I’ll need it.
The book, I Claudius, takes the Ancient Rome story from where Augustus is an old man and keeps narrating until Caligula’s death. This was the era which I was really wondering about after the end of the TV series, The Rome.
