About This Demo

Powerful monsters have appeared in Hybris. The fate of the city rests in the hands of its Heroes. 

This is the demo for Roshamboss, a 1v3 boss-battling card game based on the classic game of Rock Paper Scissors.

Roshamboss is a party-strategy game—it's like your Friday night Poker group had a baby with Among Us and they named it MTG. We recommend playing with friends using voice chat.

THE BASICS

Roshamboss is a turn-based game for 4 players. Each round, the Boss places a Rock, Paper, or Scissors "throw" face down, then the Heroes take their turn together.

Damage is dealt based on the results until only one team remains.

Here it is step-by-step:

  • Pick your preference: be the Boss or join the Heroes

  • Choose your character: every Boss and every Hero brings unique, game-changing abilities

  • The Boss goes first.

    • Step 1: the Boss picks a Target. The Target takes more damage from the Boss, or deals less damage to it (Boss's choice).

    • Step 2: the Boss places their throw face down. Every Boss has a unique gameplan, but every Boss player does it differently.

  • The Heroes respond together: each Hero chooses their own throw. Every comp enables new strategies—work together and lock in!

  • The Dare phase: after the Heroes lock in, the Boss has a choice: single out a Hero and dare them to change their choice, or start combat.

  • The Reveal phase: Combat begins when the Boss flips their card and damage is dealt based on the results. 

  • Do it again, but bigger: Strengthen your throw to deal more damage, apply Tiebreak to win on ties, Protect yourself or allies from harm, or Armor up to tank it all. 

DEMO FEATURES

The demo has limited content:

  • 3 unique Bosses: The Mountain, Talos, & Alpha

  • 5 Heroes that fit tank, healer, DPS, and support roles

  • See their cursors quiver! A shared perspective that lets you see every second guess.

  • Online lobbies with in-game text chat

  • Designed for easy pickup–at the end of the day, it’s still Rock Paper Scissors!

We’re in beta, and your feedback helps us make Roshamboss better. 

BE THE BOSS

Each boss has a unique, high-value throw, but every player knows it. If you grow stronger with every Paper you play, do you still play it? Or do you use the Heroes' fear against them and crush their incoming Scissors with a Rock?

Roshamboss is about the blend between a Boss’s built-in strategy and its player’s psychology.

  • Crush the Heroes with The Mountain, a defensive colossus 

  • Tear them apart with the rabid berserker, Talos 

  • Outwit them and end the world on your terms with the cosmic hydra, Alpha

Play it your way, but eliminate the Heroes before they pick up on your patterns.

...OR DEFEND THE CITY

As Heroes, you'll have to work together if you're going to survive:

  • Build a team from classic roles like tank, dps, healer, or support 

  • Uncover tactical synergies and big-brain teamplays

  • Earn energy through combat to spend on powerful Ultimates and Abilities

  • Play safe or go all-in with the perfect read—just don’t spread yourselves too thin!

WHAT PLAYERS SAY

  • "I can't believe Rock Paper Scissors can be this deep."

  • "It's like poker for people that want it to be more interesting."

  • "You can make a post on my Twitter if it's not paper."
