About this game
There is a tragic legend in this world...
Actually, it's not tragic at all. We just turned Rock-Paper-Scissors into a real 'Game.'
◆ Your Choices Decide the Game: <Stat Allocation>
Want to be a real man? Go all-in on Rock. If you're scared, invest in HP. But what if your opponent invested all their stats into Paper?!
The mind games have already begun against an unknown foe.
※ You can become a Gigachad, but it comes at a steep price.
◆ Legalized Cheating: The Last One Laughing Wins. <Skill System!!>
Unleash good skills, bad skills, and downright dirty skills matching each character's personality to make your enemies feel pure despair.
Attacking on a draw, forcing the enemy to repeat their hand, throwing punches before the countdown even starts—embrace your inner villain!
※ A true Gigachad who hits on a draw just to secure the win.
◆ We All Had That One Kid in the Neighborhood... <AI~ Habits>
Seriously, they exist. The classic kid who only throws Rock, or plays Rock-Paper-Scissors in strict order. But wait!
From simple habits to avoiding hands that got hurt, countering your last move, or picking their highest-damage hand—advanced AI patterns mimicking real human psychology await you. Read their mind and win. (Win rates are hidden, watch out for bluffs!)
※ She kept throwing Rock, but inside, she was playing 4D Chess.
◆ Choose Your Flavor: <Duel Modes>
[Classic Duel] : The raw, spicy taste of pure dueling! (No upgrades)
[Plus Duel] : The sweet taste of DPS brute-forcing! (Full upgrades)
◆ Wake up, Samurai... we've got gold to grind. <Upgrade System>
[Common Upgrades] : Standard reward boosts and base physical stats found in every game.
[Character Upgrades] : Standard unique stats and skill upgrades found in every game.
[System Upgrades] : Upgrading secret reconnaissance features to spy on AI patterns one by one—rarely seen in other games!
※ At the end of the day, this is Rock-Paper-Scissors. Trust your luck and gut feeling.
IT'S TIME TO DUUUUUUUUUUUEL!!!!!!!!!!!!!!!!!!!!!!!!!!!!
