TOOSIN : 투신

Your Combat Habits Become Your Next Enemy's Weapon

TOOSIN : 투신 is a third-person action roguelike where you fight an AI that remembers what you do and changes how it decides its next move.

Your go-to combos, your guard timing, even the direction you like to dodge — it all becomes combat data.

Never assume a strategy that worked once will work again in the next fight.

Enemy AI watches the range you attack from, when you guard, and which way you dodge.

The longer the fight goes on, the more its responses shift — and every habit you repeat eventually becomes a weakness.

◆ Guard, dodge, and counter tendencies that adapt to the attacks and combos you use most

◆ Combat decisions that balance spacing, closing in, pressure, and counterattacks

◆ Saved combat records that shape how enemies respond in your next challenge

◆ Check the AI's learning status and accumulated learning history mid-fight with a single button

Fail to adapt and you will be read. To survive, you must change first.

One Arena, Four Challenges

Jump straight into Ranked, Infinite Mode, Stage, or Training from the main screen, and see the records and rankings for every mode at a glance.

Stage

Break through stage after stage, earning rewards and growing stronger. Events like the Blood Contract, the Mystic Merchant, and the Challenge Chest demand a different choice every time — and when you fall, you are reborn with a new appearance and class to carry the challenge forward.

Infinite Mode

With every round, enemies grow stronger and their lineups tougher, backed by all the AI learning built up so far. Stick to one strategy and you won't last long.

Ranked Season 2

A 5v5 brawl: you and four AI allies take on five enemy AI fighters. Pledge yourself to the Blood Crown or the Ashen Oath and fight for control of the seven territories. These are single-player battles, not real-time online PvP, and are available only in the full version.

Training

Adjust your sparring partner's HP, defense, and attack, check the damage of your equipped weapons and combos, and refine chains that are all your own.

Weapons, Combos, Perks, and Traits: Build Your Own Way to Fight

Freely mix and match three classes — Warrior, Swordsman, and Fighter — with six appearances.

Leonis the Crusader, Vlad the Dark Knight, and Maximus the Gladiator unlock as you progress through the stages, and each appearance comes with its own base stats.

Weapons and Slots

Sword and shield, axe, mace, greataxe, longsword, even bare fists. Swap weapon slots mid-fight and fight the way the moment demands.

Combos

Equip separate light and heavy attack combos for each weapon slot. Every attack steps forward, letting you close the gap and keep your momentum rolling.

Equipment Screen

Pick your weapons, combos, and special abilities on a single screen, review the details, and equip.

Perks

Choose and stack from more than 20 perks during your challenge. Some perks unlock bonus effects at 3 stacks, and combining them with Blood Contracts opens the door to even bolder builds.

Traits

Over 100 traits across five branches — Strength, Agility, Vitality, Spirit, and Technique — enhance your attack sequences, positioning, parries, dodges, and ally support.

Character Info

See exactly where your HP, stamina, attack, and defense gains came from, along with your perks, contracts, and rank bonuses, all on one screen.

Pour everything into a single devastating strike, or build up stamina and defense to outlast anything.

Rapid combo chains, parry-driven counters — forge the powers you choose into a single fighting style.
