AVICI

Sin, Vengeance, and Dystopia:

In the New Millennium Era of human digitization, the totalitarian tech corporation Inya rules society through Sinergy technology. They constructed a colossal tower named "AVICI" and an energy source called "Sinergy"—converting Neohumans' sinful emotions into energy to sustain the New World. Simultaneously, Inya promised this would usher in an absolutely civilized, ideal new society.

Decades into the New World's operation, the lies were finally torn apart. Neohumans subjected to prolonged Sinergy extraction became emotionally numb, reduced to mechanical laborers; while Inya's promised utopia degenerated into gang-ruled hellscapes. The resistance group "HC" emerged. They refuse to exchange emotions for welfare and began resisting this absurd society... This Digital Revolution launched in the name of "immortality" ultimately became a technological purgatory for humanity. Beyond Jianli, Outer Entities still whisper in the shadows, awaiting the remnants of civilization's devouring.

And you—what choice will you make in the end?

From Gun to Blades: Sin is Danger, Yet Also Power

• High-speed, fast-paced Doomlike shooting experience. One shot, one headshot!

• Every consecutive kill activates a combat bonus, enhancing the speed and quality of combat.

• Defeat enemies to collect Sin Core fragments, freely choosing them to determine your killstreak bonuses.

• After five consecutive kills, activate the Sin Arm: one powerful melee weapon attack!

Sin Arms: Power or Peril?

• Before each game entry, you can choose to carry one Sin Arm. These are melee weapons inhabited by powerful Sin Consciousnesses (such as Desire, Arrogance, Greed...), each possessing unique "personalities" and combat styles.

• After using conventional firearms to achieve five consecutive kills, your Sin Arm fully charges. You can then actively unleash one powerful special attack, capable of instantly turning the tide of battle!

Classic Roguelike Experience: The Unknown Avici Journey

• Your journey is driven by a malfunctioning elevator, transporting you to unstable floors within the tower.

• Each playthrough is a fresh and randomized experience. After clearing the current floor, the elevator offers up to three (or fewer) unknown destinations to choose from.

• Make critical choices with limited visibility: Challenge stronger enemies? Seek trade and supplies? Or gamble on a high-risk, high-reward random event?
