You were a Roman Centurion back in the Wars against the Dacians. However, someone betrayed you. Now you are an Gladiator, in which your main Objective is to Survive

It's your first day at the Arenas. You prepare yourself with your humble wooden Sword that was gaved to you... but instead of Lions, Great warriors or something like that, they just sended this Grunt. He looks at you, with a evil face

"I'll Defeat you!"

He shouts, as the public at the arena watch the battle... although it were just this single dude... what will you do now?
