About This Demo

"One and Done" is a boss rush game being developed by a 3-person team.

You can choose one of four weapons to defeat enemies,
and by defeating the boss who rules over each labyrinth, you clear that map.

The available weapons are scythe, gauntlet, shotgun, and bow.

Use your preferred weapon to analyze the powerful bosses’ mechanics
and take them down.

The brief story goes like this: due to the “One and Done Project,” the villagers
were consumed by “Jam.” (Here, “Jam” refers to a mysterious black substance.
This “Jam” survives by taking living beings as hosts.)

The villagers who were consumed turned into monsters
and began attacking those around them.

However, some individuals, though consumed by “Jam,” managed to keep their sanity.
Their physical abilities were enhanced, and they could even wield weapons that normal humans couldn’t handle.

There were also those who, due to a unique constitution, were not affected by “Jam” at all.

The ones untouched by “Jam” stood against the monsters and tried to stop them.
But the monsters outside were once someone’s family and friends.

Because of this, the villagers became increasingly exhausted,
both mentally and physically.

Then one day, they learned that the mastermind behind all of this had created a labyrinth,
and inside it, was preparing the next project to wipe out the remaining survivors.
The villagers realized such a tragedy must not be allowed to continue.

But most of them could not step forward recklessly.

Then, one person declared they would go alone.

That person is the protagonist of this game, “Peace.”
And so, Peace sets foot into the labyrinth swarming with countless monsters.
