About This Demo

TOOSIN : Demo Version Notice

This demo version is a trial built to let you experience the core combat mechanics of the official release. Please note the following differences from the full game:

1. Progression Restrictions: Persistent XP, levels, perks, and gold do not accrue in the demo, and the full game's permanent metaprogression system is disabled.

2. Feature Restrictions: Steam Leaderboards, Achievements, and Cloud Save features are not supported.

3. Content Limits: You can play up to a maximum of 13 stages. Once Stage 13 is cleared, you cannot progress further.

4. Isolated Save Files: The demo utilizes a completely separate save file from the full game, meaning demo gameplay data will not carry over to the official release.

If you wish to conquer all stages, check out the full version of the game!

Surpass the AI that Learns from You - TOOSIN

TOOSIN is a roguelike action game where you fight against an AI that doesn't just repeat simple patterns, but actively learns your combat style and habits to adapt in the next run.

To survive in the arena, players must overwhelm constantly changing and evolving enemies, pushing past their own limits.

A Self-Learning AI that Adapts to Your Habits in the Next Run

Every detail of your combat habits—such as your preferred attack combos, guard timing, and dodge directions—is analyzed and digitized. Using this accumulated data, the enemy AI will enter the next run equipped with dynamic counterstrategies and workarounds tailored to your playstyle, keeping you under clever, constant pressure.

Total Enemy Adaptability Driven by the DDA System

Depending on the real-time Dynamic Difficulty Adjustment (DDA) value, all enemy behavior mechanisms, including level scaling and attack patterns, change completely. Over 20 types of enemies, each with unique patterns, evolve to become even more formidable based on your skill level, threatening your survival on the battlefield.

3 Unique Classes & Diverse Combo Action

Choose from three unique classes, each utilizing entirely different weapons and combat styles. Chain together over 20 types of strategic attack combos specific to each class to experience dynamic action with heavy, satisfying impact.

Endless Build Variety with 100 Traits, 20+ Perks, and Buffs

Combine 100 different character-strengthening traits, over 20 types of perks randomly awarded in each run, and temporary buffs from special events to craft your own unique builds. Experiment with endless combinations, maximize efficiency, and design your very own optimized combat style for a fresh experience every time.

Fate-Altering Real-Time Random Events

Dynamic, unexpected events add a layer of deep tactical decision-making, allowing you to instantly turn the tide of battle.

• Ambush System: Fend off sudden sneak attacks and claim massive rewards.

• Risky Challenges: Take high risks to secure powerful bonuses.

• Blood Covenant: Sacrifice some of your stats to explosively boost specific attributes.

• Mysterious Merchant: Spend your hard-earned gold to purchase necessary stats after clearing a stage.

Permanent Progression System

Even when you fall, your efforts are never wasted. Increase your account level with permanent EXP earned through play to permanently boost your HP, Attack, and Stamina. Start each run with more points to test even stronger and more complex builds.

Compete Globally via the Leaderboard

Compete fiercely against players worldwide based on your highest cleared stages, levels, and final scores. Become the ultimate champion and engrave your name at the very top of the global leaderboard.
