Martin runs into the man in an attempt to knock him to the ground, he then will attempt to kick him multiple times in the head and body...

The man hits the ground, and doesn't have enough energy to get back up. Martin's kick to his head puts him out cold.
The crowd cheers loudly.
Martin feels the pain of his injuries as the adrenaline wears off.

"Aggghh fuck", Martin says in pain from all of his injuries, he wipes the blood and sweat from his face and spits a heap of blood to the ground. He then, sits down in the opposite corner of the pit to where the man is laying on the ground...

"Good job! You are one step closer to your freedom. Rest now, your next fight won't be for a while."

Martin just sits there with his head in his hands...

After a while, the other man is removed. Martin is given no indication as to where he is taken. Soon, the crowd at the top gather around the pit, murmuring with anticipation.
"Five minutes until the next fight, folks!"
Another man is thrown into the pit. He is quite large and has a thick beard.

"Oh fuck", Martin says to himself

The big man recovers and cracks his knuckles.
"I am gonna make you bleed, boy."

Martin is starting to get worried... "Uh, we don't have to fight you know"

"If we don't they shoot us. Besides, I could use a little exercise. Not that you will be much of a challenge."
He smirks.

"Hmm"

"2 minutes until the fight!"
The big man rests against the opposite wall, cracking his knuckles repeatedly.

Martin stays where he is on the opposite side, he's getting really stressed out and worried now, he doesn't think that he can beat this guy...

"Fight!"
The big man steps away from the wall, waiting for Martin to make the first move.

Martin attempts to throw some sand into his face again like last time followed by a kick into his groin...
