Quick Guide
  • Shroom and Gloom beta focuses on a first-person roguelike with separate combat and exploration decks.
  • Combat Deck choices should support one focused damage plan instead of several unrelated strategies.
  • Explore Deck decisions improve routes, card modifications, weapons, abilities, and future encounters.
  • Card growth rewards repeated investment in a small group of reliable cards.
  • Early Access is scheduled for September 10, 2026, with two paths and five playable characters planned.

Shroom and Gloom Beta Overview

The Shroom and Gloom beta experience is built around a first-person roguelike double-deckbuilder. During a run, the Combat Deck handles encounters while the Explore Deck controls movement, discoveries, card changes, and progression opportunities inside the fungal dungeon. The two systems are connected: a poor exploration decision can leave the next fight underprepared, while a strong combat deck gives you more freedom to take worthwhile risks.

The beta and demo are best approached as a learning environment for the game’s central loop. Rather than collecting every available card, build a compact strategy that survives ordinary encounters, preserves healing, and grows stronger as the run continues. The official game pages describe hundreds of cards, card modification, weapons, abilities, and a journey toward The Gloom.

Combat Deck

Focuses on attacks, weapons, healing, scaling effects, and combat combos. Keep its core plan compact and consistent.

Explore Deck

Controls dungeon travel, discoveries, modifications, and opportunities that shape the rest of the run.

Card Growth

Lets important cards become increasingly powerful. Concentrate upgrades on effects you expect to play repeatedly.

Run Progression

Foresight, quests, characters, and unlocks give repeated attempts a broader purpose beyond one dungeon run.

Beta Focus

Treat each run as a test of consistency. A smaller deck with reliable damage and recovery is usually more useful than a large deck filled with interesting but disconnected effects.

The game is being developed by Team Lazerbeam and published by Devolver Digital. The planned Early Access release date is September 10, 2026. For current announcements, visit the official Shroom and Gloom page, the Steam store page, and the official developer page.

Beta Combat Deck Strategy

Combat success begins with a clear damage plan. Choose a dependable attack or weapon interaction, then add cards that improve its damage, consistency, or ability to survive difficult encounters. Healing should enter the plan early because health carries between battles. Taking avoidable damage in an easy fight can make the next room far more dangerous.

The strongest beta strategies generally follow a simple order:

  1. Establish reliable direct damage.
  2. Add healing and basic sustain.
  3. Grow the cards that appear frequently.
  4. Introduce multipliers and setup effects.
  5. Chase oversized combo turns only after the deck is stable.

Combat Roles

Card RoleValue in a RunRecommended Use
Primary DamageVery highSelect one reliable attack or weapon as the main payoff
Scaling EffectVery highApply repeated growth to cards used across many encounters
HealingHighRecover before health becomes a serious threat
Weapon SupportHighAdd effects that reinforce one chosen weapon strategy
Setup CardMedium to highUse only when a clear payoff appears often enough
UtilitySituationalKeep cards that solve a recurring weakness or improve consistency

Avoid judging cards only by their starting effect. Shroom and Gloom emphasizes cards that can grow during a run, so a modest card with repeated upgrade potential may outperform a flashy card that does not connect with the rest of your deck. This is especially important when selecting between a new card and an improvement to an existing one.

Avoid Deck Bloat

A new card is not automatically an upgrade. If it makes your strongest attacks, healing tools, or combo pieces harder to draw, skip it unless it directly solves a meaningful weakness.

Four Practical Build Archetypes

BuildCore CardsDifficultyMain Strength
Balanced GrowthReliable attack, growth, healing, light utilityBeginnerStable progression with flexible decisions
Weapon ComboWeapon, support effects, scaling, healingIntermediateFocused damage with strong synergy
Infinite GrowthRepeatable growth, one or two damage cards, sustainIntermediateVery high late-run scaling
Mega Damage ChainHigh-growth attack, multipliers, setup, amplifiersAdvancedExceptional payoff after the engine is assembled

The Balanced Growth Build is the safest starting point. It teaches the relationship between damage, healing, and upgrades without requiring a precise sequence. The Weapon Combo Build is a natural next step when you find a weapon that clearly fits your available support cards.

The Infinite Growth Build works best when you resist unnecessary additions. Concentrate improvements on one or two frequently used cards, maintain enough recovery to survive the buildup, and allow the deck’s power to compound across later encounters. The Mega Damage Chain is more demanding because it accepts weaker early consistency in exchange for a larger final payoff.

Explore Deck and Progression Walkthrough

The Explore Deck is not a secondary system. It determines how effectively you move through the dungeon, which opportunities you reach, and how prepared your Combat Deck becomes before a difficult encounter. Use exploration actions to strengthen your long-term plan rather than taking every risky reward.

1

Read the Next Risk

Before committing to an exploration choice, consider your current health, Combat Deck quality, available healing, and whether the next encounter is likely to demand immediate damage. A reward is less valuable when it leaves you unable to handle the next room.

2

Modify Core Cards First

Prioritize card modification for attacks, weapons, healing tools, and scaling effects that already support your main plan. Improving a frequently played card gives value across more encounters than upgrading an option that rarely appears.

3

Compare New Weapons and Abilities

New weapons and abilities can change the direction of a run, but do not take them automatically. Choose them when they reinforce your current deck or offer a clear solution to an existing weakness.

4

Prepare Before Dangerous Fights

Use remaining exploration opportunities to improve survivability, clean up the deck’s strategy, and preserve enough recovery. Entering a major encounter with stronger core cards is safer than saving every resource for an uncertain future reward.

Exploration Priorities

Exploration ChoicePriorityWhy It Matters
Core card modificationVery highImproves cards that already define the run
Compatible weaponHighCan become a long-term combat engine
Useful abilityHighExpands options when it supports the deck
Healing opportunityHigh when damagedProtects progress before the next encounter
Risk-reward optionSituationalStronger when health and deck quality are secure
Unrelated new cardLowMay reduce draw consistency without improving the plan

Foresight adds a longer-term layer to repeated attempts. Progression choices should generally favor unlocks that expand future deck-building options, character access, or card availability. However, do not undermine a promising run simply to force every progression objective at once. The goal is to make future attempts broader while still giving the current run a reasonable chance to reach The Gloom.

Progression Rule

Prioritize unlocks that remain useful across multiple future runs, especially new characters, broader card options, and systems that improve strategic flexibility.

As Early Access expands, the game is expected to include two independent paths, five playable characters, numerous quests, and separate character card pools. The currently identified roster includes Paperboy, Lunch-lady, Concerned Parent, Janitor, and Activist. Exact unlock requirements may change during development, so verify quest conditions against official patch notes and announcements after each major update.

Health, Enemies, and Run Safety

Health management is one of the most important skills in the beta. Combat rewards large combos, but an oversized turn is not always the correct choice if it requires several setup cards while an enemy continues attacking. Against routine enemies, remove threats efficiently and preserve recovery. Against dangerous encounters, prioritize a reliable line that reduces incoming damage.

Encounter Preparation

Encounter TypePrimary ConcernRecommended Approach
Standard fungal enemyUnnecessary chip damageUse efficient attacks and avoid prolonged turns
Multiple enemiesSeveral sources of incoming damageRemove one threat quickly before spreading damage
High-damage encounterLosing health before setupUse direct damage, healing, and dependable defensive tools
Biome bossDeck consistency checkUpgrade core attacks and enter with healthy resources
Late-run encounterWeak draws and diluted strategyKeep the deck focused and preserve recovery

In multi-enemy fights, reducing the number of active attackers is often safer than distributing small amounts of damage across the entire group. A compact Combat Deck makes this decision easier because key attacks and healing cards appear more reliably.

Before a boss or difficult room, review four questions:

  • Can the deck deal meaningful damage without its perfect combo?
  • Is enough healing available to recover from an imperfect draw?
  • Are the most important cards receiving the majority of upgrades?
  • Will the next exploration choice improve preparation or create unnecessary risk?

Before Entering a Difficult Encounter:

  • Confirm the Combat Deck has a reliable primary damage plan
  • Keep healing available when current health is already pressured
  • Upgrade a frequently played attack, weapon, or scaling card
  • Remove or avoid cards that dilute the central strategy
  • Use the Explore Deck to prepare instead of chasing every risky reward
Survival First

A smaller reward that preserves health can be more valuable than an aggressive exploration choice that makes the next combat encounter unsafe.

The Survival Combo Build is useful for learning these decisions. It combines efficient attacks, healing, controlled growth, and limited defensive utility. This approach gives up some maximum damage potential but provides more room to learn enemy patterns, route choices, and card interactions.

Early Access Preparation and FAQ

The beta is a useful foundation for learning the game’s vocabulary and deck relationships before Early Access begins. Focus on understanding why a card belongs in a build rather than memorizing an isolated ranking. Since the game is still expanding, broad strategic principles are more durable than assumptions about final card values or exact unlock requirements.
