Gladiator. The origin

You are a group of adventurous friends, who thanks to a space/time moment, have appeared, no less than in the era of the great Caesar Augustus. But from here on, troubles arise. The hole opened in time has taken you to one of the cells of the Great Circus of Rome, and the centurions are eager to throw you to the lions. As good gladiators, you must fight against all misfortunes that arise in your path. For this, you will have the help that other travelers who had tried before had left you, and they were leaving clues throughout the tunnels, but few managed to get out alive from the Great Roman Circus.
