Pairs well with
The FroGames Card
You open the box, unlock Goblin and Dryad, combine Paladin or Shaman. Then you scan the first card and the jungle boss makes you realize the base game was just a warm-up.
WHAT IT'S ABOUT
The jungle tests you (and eliminates you if you're not ready)
Jungle Fever is the expansion for Boss Fighters QR, the hybrid cooperative game by Michael Palm and Lukas Zach that everyone was talking about at Essen 2025. This expansion introduces five jungle bosses, tougher and more treacherous than those in the base game, and two new heroes (Goblin and Dryad) with two new classes (Paladin and Shaman). New loot cards unlock combos that didn't exist before, and bosses punish you if you think you can use the same tactics from the first campaign cycle.
The base game is mandatory to play this expansion. The app recognizes new cards via QR code, bosses react in real-time, and the jungle introduces mechanics that force you to discover hidden weaknesses as the game timer ticks down. Each boss has unique patterns, and the official recommendation is clear: only face them after defeating the 10 in the base game. It's not advice, it's a warning.
What they say abroad
"The app brings that PC experience of me/us against a boss to the tabletop"
The app brings the PC experience of me/us against a boss to the tabletop
— Pegasus Spiele
Jungle Fever raises the bar: bosses are more treacherous, combos more necessary, and every mistake is costly. If the base game already felt tense, prepare to discover what it truly means to lose against an intelligent automaton.

Boss Fighters QR: Jungle Fever
What's in the box
Two heroes, two classes, five bosses, and loot cards that change the meta
Goblin and Dryad (new heroes)
The Goblin plays dirty (trick cards and unexpected damage), the Dryad manipulates the field and regenerates. Both combine with all base game classes.
Paladin and Shaman (new classes)
The Paladin absorbs hits for the team, the Shaman amplifies allies' moves. Two opposing philosophies, same necessity: close coordination.
5 jungle bosses
More complex patterns than the base game, immediate punishments for timing errors, and hidden weaknesses the app won't reveal. Only face them after the 10 from the base game.
Exclusive loot cards
New equipment that unlocks previously impossible combos. The cards integrate with the base game's loot system and can be used against all bosses, even the original ones.
🎲How to playThe rules in four steps▼
How to play
The flow of each round
Identical to the base game, but jungle bosses punish you more if you waste actions.
The boss generates a shield for each damage type (Melee, Ranged, Magic). You must break the correct shields before attacking.
Each hero has 3 turns, one for each action. You play a card, scan it with the QR code, the app applies the effect, and the boss reacts. Timing and order matter.
If you haven't reduced the boss's attack to zero, you take damage. If a hero reaches 0 health points, the team immediately loses.
Draw cards until your hand is full. The boss prepares for the next turn. The app tracks progress, statuses, and unlocked loot cards.
⏱️Your first gameThe chronicle, moment by moment▼
A game in five moments
What happens at the table
Not the rules. The experience.
Setup with the new hero
Choose Goblin or Dryad, combine them with Paladin or Shaman (or base classes), shuffle the two decks, and discover that 12 starting cards seem few when facing a jungle boss. The app loads the first enemy and warns you: this is not the tutorial.
The boss reacts
You play the first card, scan it, and the boss doesn't wait. It changes tactics, activates an unforeseen shield, and punishes the most obvious move. You immediately understand that the base game strategies are not enough.
The cooperative turning point
The Paladin absorbs damage for the Goblin, the Shaman amplifies the Dryad's attack. The new synergies change the rhythm: now each turn is a chain, not a single move.
The boss eliminates you (or almost)
A timing error, a card drawn at the wrong moment, and the boss brings you to zero health points. Someone sacrifices a resource to save you. Or not, and you start over.
Victory or reset
Either the boss falls and you unlock new loot that will make the next encounter different, or you lose and start over with a better plan. No one leaves without having learned something.
🐸What to know beforehandThree honest things, from friends▼
What to know beforehand
Three things you need to know before buying Jungle Fever
Requires the base game
Mandatory. You cannot play with only the expansion: you need the board, tokens, base components, and the app already installed. Jungle Fever adds cards and bosses, not a standalone game.
Mandatory app and connection
The app is free (iOS/Android) but essential: without it, the bosses do not exist. You need a smartphone or tablet with a working camera and enough space. The app must recognize QR codes.
Higher difficulty than the base game
Pegasus explicitly recommends tackling the 10 base bosses first. Jungle bosses have more complex patterns, immediate penalties, and require optimized decks. If you're new to the game, wait.
🏆Victory and defeatWhat the ending rewards▼
How it ends
How to win and how to lose
Clear objectives, immediate consequences. Each boss has its own victory condition, but defeat is always the same.
Victory
- Reduce the boss's health points to zero before your team is eliminated
- Unlock new loot cards to integrate into your decks for subsequent bosses
- You can face the same boss at a higher difficulty (Beginner → Insane)
Defeat
- Even if only one hero reaches 0 health points: the team immediately loses
- The boss activates a special defeat condition (varies for each enemy)
- You restart the battle, but the app tracks progress and loot remains unlocked
Jungle Fever is for those who have already mastered the base game and want more unfair bosses, tighter combos, and more punitive defeats. If you haven't finished the original 10 bosses yet, come back here later.

Frequently Asked Questions
FAQ about Boss Fighters QR: Jungle Fever
Can I play Jungle Fever without the base game?
No. The expansion requires the Boss Fighters QR base game: you need the physical components (tokens, health tracks, loot boxes), the app already installed, and knowledge of the rules. Jungle Fever only adds heroes, classes, and bosses.
Do the new classes and heroes work against the base game bosses?
Yes. Goblin, Dryad, Paladin, and Shaman combine freely with heroes and classes from the base game, and you can use them against all 15 bosses (10 base + 5 jungle). Jungle Fever loot cards integrate with the existing pool.
Is it really harder than the base game?
Pegasus explicitly states that jungle bosses are designed for those who have already completed the base cycle. More complex patterns, immediate penalties for timing errors, hidden weaknesses. If you're new to the game, wait.
What mechanics does Boss Fighters QR: Jungle Fever use?
Progressive cooperative deck-building, Scan & Play (QR codes read by the app in real-time), hand management, variable powers, dynamic boss battles with reactive AI. Identical to the base game, but jungle bosses stress them more.
Is it available in Italian?
No. Jungle Fever is available in the English edition. Texts on all cards (heroes, classes, loot), but the app supports Italian for the interface (the base game already has app localization). Basic knowledge of English is recommended for the cards.
