Temtem: Swarm launched into full 1.0 release on April 2, 2026 for PC and PlayStation 5, with cross-platform play included from day one. Developer Crema Games built this bullet heaven spin-off after the team played Vampire Survivors together — and that origin story shows in the best way. You pick a Temtem, survive relentless waves of glitched creatures for 20 minutes, and then face a giant boss. Simple premise, genuinely tricky execution.
What is Temtem: Swarm, exactly?
Temtem: Swarm is a bullet heaven (also called a Survivors-like) where up to three players each control a single Temtem inside the depths of a Temcard. The goal is straightforward: survive a 20-minute run against escalating swarms of wild, glitched Tems, then take down the stage's final boss. That boss is an oversized version of a Temtem, and on first encounter it will absolutely humble you.
Death is baked into the design. You're meant to die, collect Pansun (the in-game currency earned during runs), and spend it on permanent upgrades before trying again. The loop is familiar to anyone who has put time into Vampire Survivors or Brotato, but the creature-collecting DNA from the original Temtem MMO gives it a distinct personality.
According to the review published by Rogueliker on April 1, 2026, the game is "genuinely approachable for beginners and younger players," with Tems being tankier than you might expect from the genre. That forgiveness is real — early runs feel exploratory rather than punishing.

You don't need any experience with the original Temtem MMO to enjoy Swarm. The callbacks and Easter eggs are there for returning fans, but the game stands entirely on its own.How does the skill tree system work?
Each playable Temtem has its own branching skill tree, separate from every other creature in the roster. Spending Pansun here unlocks permanent stat improvements — things like base damage, critical hit chance, and special abilities. Because the trees are individual, you're not spreading upgrades thin across the whole roster. You can go deep on one Tem and genuinely feel the difference.
This is one of the smarter design decisions in Swarm. It means your Nessla build plays nothing like your Oree build, and grinding runs with a specific Tem actually has a payoff beyond just familiarity. The Rogueliker review specifically calls out the individual skill trees as "a smart move, letting you tailor your creatures to their individual strengths."
Oree's branching skill tree
What upgrades should you prioritize first?
Based on available information from sources, the skill tree covers base damage, critical hit chance, and special abilities. Since runs end at 20 minutes (or earlier if you die), damage output determines how fast you clear the field and how many upgrade drops you can collect mid-run. Prioritizing base damage early keeps your Tem relevant through the mid-run difficulty spike. Critical hit chance becomes more valuable once base damage is already solid.
Special abilities vary by Temtem, so check the Official Temtem Swarm Wiki for creature-specific breakdowns before committing Pansun to a tree you haven't tested.
warning
Don't spread Pansun across every Temtem's skill tree at once. Pick one or two Tems you actually enjoy playing and go deep. A half-upgraded roster of eight Tems will lose to a fully upgraded Nessla every time.
Which Temtem should you pick?
The full roster sits at 13 playable Temtem, with that number growing slightly when you factor in evolutions. Only two are available from the start. The rest unlock through two methods: beating bosses and completing egg hatching events.
The egg hatching events are the slower path. You have to defend an egg against incoming waves while simultaneously managing upgrades and staying alive. The Rogueliker review describes this as "a bit of a slog," and after spending time with it, that's fair. It's not broken, just repetitive when you're already juggling a lot.
Fan-favorites from the original game that appear in Swarm include Nessla, Oree, and Yowlar, alongside the starter trio. The selection is solid even if 13 feels like a modest number for a full 1.0 release.
info
Evolutions are available during runs and provide powerful stat boosts to your Temtem. Evolving mid-run is one of the biggest power spikes you can trigger, so plan your upgrade path with evolution in mind.
How does co-op change the experience?
Up to three players can run together, each controlling their own Temtem. According to the Rogueliker review, playing with friends online "makes for an even more relaxed learning curve." That tracks — having two other Tems on the field means the swarm's attention is split, and coordinated builds can cover each other's weaknesses.
Solo play is completely viable, and the game's tanky design means you're never dependent on teammates to survive early runs. But co-op genuinely changes the pacing. Bosses that feel overwhelming in a solo first encounter become much more manageable with two or three players coordinating evolutions and upgrade timing.
The 1.0 release also brought the game to PlayStation 5 with full cross-platform play between PC and PS5, as confirmed by Crema Games in their release trailer. A Nintendo Switch version is in development but had no release window as of the 1.0 launch, according to reporting by Massively Overpowered.
Three-player co-op in action
What happens during a run?
A standard run has a clear structure. You survive waves, level up, and choose upgrades and moves as you go. Mini-challenges appear throughout — these include tasks like defeating bosses within a run or destroying as many boxes as possible before a timer runs out. Completing them earns additional rewards, which feed back into your permanent progression.
The 20-minute timer is your constant pressure. The final boss appears after you clear it, and these bosses are giant Temtem that hit significantly harder than anything in the regular waves. First encounters with new bosses are designed to be difficult, so don't be surprised if you lose the first time you meet one. That loss still earns Pansun, which goes toward the skill tree upgrades that make the next attempt easier.
End-of-run boss encounter
What's the best way to spend Pansun between runs?
Focus on the Temtem you're actively running. Every Pansun spent on a creature you're not using is Pansun that didn't make your current runs harder to fail. Once your main Tem has solid base damage and a couple of ability upgrades, you can start branching into a second Tem for co-op variety or boss-specific matchups.
The Patch 1.8 notes on the official Temtem Wiki cover the last major content update to the original Temtem MMO, which went into maintenance mode in 2024. Swarm is a separate product and operates independently, but players curious about the broader Temtem universe will find context there.
Is Temtem: Swarm worth playing in 2026?
For fans of the Survivors-like genre, yes. The individual skill trees give it more long-term build depth than a lot of similar games, and the co-op implementation is genuinely fun rather than tacked on. The roster of 13 Temtem is smaller than you might hope at full release, and unlocking new creatures through egg hatching events can drag. But the foundation is strong.
For players coming from the original Temtem MMO, it's a nostalgia trip that actually works as a game. The locales, music, and creature designs carry over, and seeing familiar faces like Nessla and Yowlar in a completely different genre context is a genuine treat.
