1. Game Overview

Deck of Haunts puts you in control of a malevolent mansion that lures unwary explorers into its shifting halls. Each run spans consecutive nights: spend essence by day to expand rooms and reroll your deck, then survive waves of intruders by night using haunt cards to inflict physical and mental damage.

• Release Date: May 7, 2025 (PC via Steam)
• Genre: Roguelike deckbuilder with turn-based puzzle strategy
• Core Loop: Build by day → haunt by night → harvest essence → repeat
• Win Condition: Defend your Heart Room for a set number of nights

2. Day & Night Phases

Each cycle divides into:

1. Day Phase: Spend essence to add, upgrade or rearrange rooms; reroll starting cards or unlock relics in the Research Lab.
2. Night Phase: Intruders spawn and wander; play cards to deal Damage, apply Drain or lay Traps; collect essence from vanquished visitors.

3. Mansion Construction

Room placement dictates visitor paths and exposure to hazards. Proven layouts include:

1. Single-Path Corridor: A straight sequence of rooms with escalating effects ensures every visitor triggers your best traps
2. Spider Web: Branch multiple dead ends from a central hub to isolate intruders and handle them one at a time
3. Choke Points: Place high damage or high drain rooms just before the Heart to punish survivors in final stretches

4. Card Mechanics

Your deck consists of Haunt cards categorized into Damage, Drain and Trap types:

• Ideal Sequence: Build Tension → Drain sanity → Deal Damage for max essence payout.
• Card Costs vary, so balance your hand to avoid being stranded with high cost cards early.
• Relics can modify card behavior, unlock in the Research Lab during Day Phase.

5. Intruder Types & Traits

Visitors vary in resistances and behaviors, so tailor your rooms and cards accordingly:

6. Essence & Resource Management

Essence fuels Day Phase expansions. Maximize nightly harvest by:

1. Executing a “double-tap” on each intruder: Drain sanity then Damage for full essence value
2. Building Phobia/Torment combos to stack Tension multipliers before Drain.
3. Rerolling decks early if you lack low cost Drain or Damage cards.
4. Saving at least 20 essence per day for critical Research Lab rerolls.

7. Deck Building & Progression

Each successful night grants a choice of two new cards to add permanently. Your deck growth drives your strategy:

1. Early Runs: Prioritize low cost Drain and Damage cards for consistency.
2. Mid Runs: Add mixed Trap cards to reinforce high traffic rooms.
3. Late Runs: Include high impact cards (Mass Drain, Echoing Bell) to handle boss waves.

Meta-progression unlocks new card types, room templates and relics across runs, deepening strategic options as you progress through the Mansion’s tiers.

8. Advanced Layout Strategies

1. Status Corridor: Alternate Phobia and Torment rooms to build Tension before final kills.
2. Bell Curve: Centralize Bell Tower rooms to stun clusters mid path and isolate stragglers.
3. Dead-End Exploit: Force Priests into isolated loops for high yield Drain combos.
4. Dynamic Redirects: In demo v2.0, reposition doors mid build to reroute survivors into fresh traps

9. Hard & Challenge Modes

• Hard Mode: Increases intruder HP and removes friendly build guarantees which requires tighter deck and room synergies.
• Endless Challenge: Survive as many nights as possible, The mansion grows vertically with new room tiers unlocked every 5 nights.
• Speedrun Tips: Use early Bell Tower stun combos and focus on essence rush to unlock relics that boost card draw.

Conclusion

By combining optimized layouts, precise card sequencing and effective essence farming, you’ll turn your haunted mansion into an unstoppable fortress. Prioritize double tap Drain–Damage combos, refine room paths and expand your deck strategically. Now, jump into your next night’s haunt and trap every explorer!
