Immunica merges mouse-based action combat with incremental management—hover your cursor to destroy pathogens while building out a research lab, recruiting scientists, and advancing toward vaccine development. Weapons fire automatically as hordes attack, letting you balance active play with passive progression through skill trees and upgrades. It's accessible enough for newcomers but may feel grindy for veterans seeking deeper strategic variety.

Idle & Incremental Lovers recommends Immunica, but with caution :
Immunica does a lot of things right and is an OK game in its genre. Gameplay is basic, but fun and active. Slow-paced progression and lack in upgrades variety make it feel too grindy, though.
Also noteworthy
* 4 skill well organized skill trees, but very repetitive and a lot of pure "number go up" repetitive upgrades.
* The research lab adds a small layer of gameplay, as well as a prestige system.
* Dev responded to player criticism by rebalancing the entire game (it was nearly impossible to beat at first), which is great.
* The game overstays its welcome, endgame felt like an unncessary grind.
Why didn't the biochemist laugh at antibody jokes? Cause he was humorally immune.

Discovered the game because of PolishOurPrices.
Tutorial is too much text at once but the game is super intuitive and easy to get into so it's not a problem.
There is not enough time to read effect descriptions at the start of the round, but not reading them does not really hurt experience of the game.

But to leave it all with good taste, it's super addictive, easy to get into and the rounds are quick. Good both for 1 hour and 1 minute of playing.

Functionally this should be titled Early Access

Currently with literally EVERY upgrade and "prestige" available the game is quite literally impossible to complete (not that it seems to have an end screen)

You can reach this point in under 30 minutes and then bash your head against no progress

Enemies gain 1000% health to your 50% damage quite quickly at that point

Rows no longer squeeze together or overlap on wide or short screens.LabYou can now move and sell equipment. Click any placed equipment to open its menu.Move: the equipment follows your cursor. Left click places it, right click or ESC cancels.Sell: you get back half of the equipment's price in Protein.Researchers no longer stand on top of each other, even with more than 10 researchers.Two researchers no longer work at the same station.Dragging a researcher onto a station that is already in use now swaps the two researchers.Fixed researchers sometimes getting stuck and not walking to the sample shelf.Equipment placement rules now work the same in every direction. Before, a station could go next to a shelf, but a shelf could not go next to a station.The research complete popup no longer blocks clicks.Fixed missing and broken icons in the Lab interface.The back button in the Lab now returns you to the upgrade tree if you came from there. Before, it started a new run.I am also working on a bigger update with new gameplay. More news soon. My New Game: Feed The Pond I am also making a new game called Feed The Pond. It is a cozy incremental game about a swamp creature called the Wart, who is always hungry. You hire frogs, brew potions and turn a quiet little pond into a bubbling swamp machine. The free demo comes out on Steam on November 3. If you enjoy Immunica, I think you will like it too. Wishlist the game: Play the demo on November ...

Hey everyone!Thank you so much for playing Immunica. Every review, every bug report and every #polishourprices comment taught me a lot about making games.Now I'm working on something new: Feed The Pond. Deep in the swamp lives the Wart. It's big, it's lumpy, and it's always hungry. Hatch frogs to catch flies, pick flowers and dig up mushrooms for it, brew potions in a bubbling cauldron, and watch the swamp slowly start running itself.It's a calm, relaxing incremental with hand-drawn art. Wishlisting really helps a lot. Thanks for being here 💚eranboi

Massive Balance Overhaul: The True Incremental Experience!

210 days ago
Hello! Thank you so much for playing Immunica and leaving your reviews. I have read your feedback carefully, and I agree with you: the progression curve felt off. Many of you hit a wall where you maxed out all your upgrades too quickly, while the enemies kept getting stronger. This left you feeling underpowered and unable to complete the game. In an incremental game, you should feel stronger over time, not weaker. Today, I am releasing a massive balance overhaul that fixes this issue. Here is what is new: Economy & Progression Overhaul No More Early Caps: I have completely re-scaled the upgrade costs and extended the progression curve. You will no longer max out all upgrades in the first couple of hours. The progression is now much deeper, giving you continuous and meaningful goals over hundreds of runs. Massive Weapon Scaling Out-Scale the Swarm: Previously, weapon damage capped out too low compared to the late-game enemies. To fix this, I have drastically buffed the Base Damage and Upgrade Scaling of the Burst, Missiles, Drones, and Beams. Late-game weapons now scale like true ultimate weapons. If you invest in them, they will easily shred through the pathogens that used to block your path. Survival Balance Meaningful Defenses: The interaction between your Health, Armor, Resilience, and the enemies' collision damage has been reworked. With the new HP scaling and defensive tweaks, you now have the tools to survive the late-game Alpha pathogens as long as your offense keeps up. Jump back into the bloodstream, keep upgrading your arsenal, and experience the late-game progression as it was meant to be. Let me know how far you can push the numbers in the new economy. Happy purging!
