About Lethal Dungeon

Lethal Dungeon is a strategy-based roguelike card game from Nihohe Soft that dropped on PC in 2026. It’s all about efficiency and risk management. You start each floor with a fixed hand of five cards and must defeat enemies in a single turn. The twist? You can only use your initial draw or spend earned currency to reshuffle and redraw. The goal is to clear the dungeon by upgrading your deck through smarter spending and smarter play. It’s a minimalist approach to turn-based combat, with a focus on resource scarcity and incremental upgrades. Fans of tactical puzzle games will recognize the tight feedback loop between spending, earning, and optimizing. The genre blend of RPG and strategy feels sharp, with progression tied to both luck and skill.

Gameplay

Each session is a grind through procedurally generated floors. You begin with five cards, but only the ones you can afford to redraw. Enemies vary in health and attack patterns, forcing you to adapt your hand’s composition mid-turn. For example, a high-damage enemy might require a combo of low-cost burn effects and a single heavy hitter, but if you overextend your resources, you’ll stall. Money is earned by defeating foes, but it’s scarce, reshuffling costs 10% of your current balance, so you learn when to play aggressively and when to reset. Deck upgrades unlock new cards, but you’re limited to 40 slots, so prioritizing synergies matters. Battles are tense, often hinging on whether you can chain effects or force enemies into low-health states. The loop is punishing but addictive, with each run teaching you how to optimize for the next.

What Players Think

PlayPile users gave Lethal Dungeon a 4.5/5 rating, with a completion rate of 37% and an average playtime of 12.6 hours. Metacritic averages 78. Community moods are split: 42% call it "Addictive," 31% "Frustrating," and 19% "Rewards Skill." A top review notes, "The tension between resource scarcity and deck-building payoff is unmatched, but the learning curve is brutal." Only 21% of players hit 100% completion, while 58% complete the main dungeon. Achievement data shows 50 total trophies, with 35 hours needed for full completion. Players who clear the game without reshuffling more than twice per floor earn a 3.8% bonus to rewards, per in-game stats.

PlayPile's Take

Lethal Dungeon is a must-play for fans of resource management and tactical card games. Priced at $29.99, it offers 10-20 hours of high-stakes puzzle-solving, but the difficulty curve can alienate casual players. The 50 achievements feel earned, not grindy, and the 37% completion rate reflects its punishing design. If you enjoy tight optimization loops and can tolerate its ruthless difficulty, it’s a deep, rewarding challenge. But if you prioritize accessibility or open-ended exploration, skip it. The game’s strength lies in its simplicity and the thrill of mastering a broken hand.
