About This Demo

Your Combat Habits Become Your Next Enemy's Weapon

TOOSIN : 투신 Demo is the trial version of TOOSIN : 투신, 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.

What's in the Demo

Stages 1–15

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 in the final stages, 13 to 15, elite enemies lie in wait.

Infinite Mode

With every round, enemies grow stronger and their lineups tougher, backed by all the AI learning built up so far. See how long you can last.

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.

Enemy AI That Learns

Enemies watch the range you attack from, when you guard, and which way you dodge — and change how they respond. Check what the AI has learned mid-fight with a single button.

Weapons, Combos, and Special Abilities

On the Equipment Screen, pick light and heavy attack combos and special abilities for each weapon slot and equip them, then swap weapon slots mid-fight as you battle.

Perks and Traits

Choose and stack perks during your challenge, and use traits to enhance your attack sequences, parries, dodges, and support — build a fighting style all your own.

Demo-Exclusive Leaderboards

Your Stage and Infinite Mode records are posted to demo-exclusive Steam Leaderboards.
