Late Stage Gambling

 BET BEFORE YOU FIGHT
The slot machine is your armory. Before every wave, gamble for weapons, buffs and consumables. Then take your winnings into the arena and put them to work.
Nobody makes you bet, though. We respect your free will. (Punishments may apply.)
 

HIGHER STAKES. HARDER FALLS.
Bet small for modest rewards, or raise the stakes for stronger gear. Just remember: the bigger the wager, the harsher the punishment when you lose a bet. How much are you willing to risk for a better shot at surviving the next wave?

LUCK WON’T PULL THE TRIGGER.
A lucky spin can get you a better gun. Staying alive is still your problem. Shoot, stab and tear through waves of enemies with the gear you gambled for. Survive the bloodshed, then decide how much to risk all over again.

EVERYONE DOWN THERE OWES SOMETHING

There's a price on your head, and it's exactly large enough to clear the debt of whoever collects it. People from all around the world come into the arena, each one of them is fighting for the same reason you are, to pay their debts with other people's blood. 

Well... to be honest, no one really cares about paying their debts.

Blood is money. And money means one more bet on 19.
