All 5 classes ranked S to C - Medic, Engineer, Juggernaut, Bomber, Outlaw - what each is weak against, and how to unlock the top two with Gems.
Survive a Million Monkeys Class Tier List
There are five classes in Survive a Million Monkeys and this is the only ranking of them anywhere: Juggernaut and Bomber sit on top, Medic just behind, then Outlaw and Engineer. Nothing about the game has published damage, cooldown or Gem price data yet, so the tiers below rank role fit in a horde shooter and flag every claim that is not sourced.
- S tier: Juggernaut, the class coverage keeps calling high-tier and the one most players save Gems for.
- A tier: Bomber for crowd clearing, Medic for keeping a 25-player server alive.
- B tier: Outlaw, a damage-first pick that needs space to work.
- C tier: Engineer, a utility pick whose value depends entirely on your squad.
The five classes at a glance
The official listing sets the frame without naming them: choose your class, unlock powerful guns, fight massive hordes together, climb the survivor leaderboard. The five names below are the roster every source agrees on.

| Tier | Class | Role read | Strong when | Weak when | Unlock status |
|---|---|---|---|---|---|
| S | Juggernaut | Frontline survivor | Waves get dense and you need to hold ground | Slow kills against spread-out targets | Gems unlock, per Destructoid |
| A | Bomber | Area damage | Big crowds, especially with the Blasting Off monkey variants | Solo play against a handful of monkeys | Gems unlock, per Destructoid |
| A | Medic | Team support | Full servers where 24 people need covering | Solo runs with nobody to keep alive | Not published, treat as a starter pick until you check |
| B | Outlaw | Damage dealer | Open ground where nothing can reach you | Anything that closes the distance | Not published, treat as a starter pick until you check |
| C | Engineer | Utility | Groups that coordinate and use what you give them | Playing alone or with randoms | Gems unlock, per Destructoid |
Skill text, cooldowns, health values and Gem prices are all unconfirmed for every class in the game. If a tier list quotes exact cooldowns or exact prices, those figures were invented somewhere along the way. This ranking uses role function in a horde shooter plus what published coverage has actually said, and stops there.
S tier: Juggernaut
Juggernaut is the class the game's own coverage leads with. Destructoid's codes write-up opens by framing Gems as the way to reach the devastating Juggernaut class, and its reward copy puts Juggernaut and Bomber together as the high-tier unlocks worth saving for.
The role reads as a frontline survivor, which is exactly what density rewards. In a game where the difficulty curve is how many monkeys arrive at once, the pick that keeps you upright while the crowd closes is worth more than the pick that kills faster. Juggernaut also plays well in co-op, because the front position is the one most likely to be covered by teammates behind you.
The catch is slow single-target damage. If you are the only player on the server and the monkeys trickle in one at a time, a survivability class outlasts the fight and nobody scores.
Both are the unlocks that coverage singles out as high-tier, and both are Gems purchases rather than starter picks. The Gems guide covers how to fund the purchase without breaking your upgrade budget.
A tier: Bomber
Bomber is the other high-tier unlock, and its timing lines up with the Blasting Off update that added explosive banana attacks and dangerous new monkey variants. Area damage classes get better as the enemy mix shifts toward denser groups, and that is the direction this update pushed the game.
Bomber is a worse pick than Juggernaut for a solo first run, where the monkeys come in ones and twos and area damage has nothing to hit. It is a better pick the moment a server fills up, which happens constantly at this player count.
A tier: Medic
Medic scales with the size of your group rather than with your own skill. In a 25-player server, one player covering the other 24 is worth more than one player dealing damage, because the whole run ends the moment the front line breaks. This is the class that makes a group of friends last longer than a group of strangers, and it is the reason a co-op lobby with one Medic is a different experience from an empty one.
Solo, it drops. Nobody is there to benefit from it.
B tier: Outlaw
Outlaw is the damage-first option in the roster and the most position-dependent. It rewards players who keep distance and punish players who get surrounded, which makes it a strong pick in open sections of the map and a liability in a scrum.
The reason it sits below Medic is not that damage is weak, it is that damage does not keep you alive once the horde reaches you. A class that kills three more monkeys before contact buys you three more seconds. A class that survives contact keeps the whole server standing.
C tier: Engineer
Engineer is described by coverage as one of the specialized classes that Gems unlock, which means it costs currency before you have proven you need it. Its value depends on teammates who know what you do and adjust around it. That is a real payoff in a coordinated group and close to nothing in a public server full of players who are ignoring you.
That is the whole argument for the C tier. It is not a bad class, it is a class that asks for something from the other 24 people in the room.
How this ranking will change
Blasting Off already shifted the meta by adding variants and projectiles, and the game's listing shows it was last updated on October 4, 2026. The moment official numbers land, this page becomes an arithmetic exercise instead of a role argument. Watch the group page and the Discord, both linked below, because that is where the developer posts changes first.

FAQ
Which class is best in Survive a Million Monkeys?
For most players, Juggernaut. It is the class coverage treats as high-tier, and survivability is what a horde shooter rewards. Bomber is the pick if you mostly play in full servers.
How do I unlock Juggernaut?
With Gems. It is one of the classes coverage describes as a Gems purchase rather than a starter pick, and the two live codes pay 2,000 Gems between them.
Is Medic worth playing?
In a full server, yes, because support scales with group size. Solo, it is the weakest pick on the roster for the reason above.
Which class is worst?
Engineer, if you are solo or playing with randoms. It is not a bad class, it is the class most dependent on teammates cooperating.
Do classes change with the class tier list updates?
Classes do not change. Their ranking here will, as soon as the developer publishes real numbers or a patch shifts the balance. The beginner guide explains which pick suits your first run.
