Want to know more about Theater Mechanicus in Genshin Impact? If the name seems familiar, that's because this limited-time event first ran in version 1.3 back in February. Now it's arrived in Inazuma, so if you missed out on this minigame the first time around, you've got just over a week to give it a try.

Theater Mechanicus is essentially a table-top game from Liyue, though you get to play inside the game as if it were a dungeon or domain. You can earn a unique event currency for completing each stage which you can then spend at the event shop. It's not sticking around forever though, so if you're keen to jump straight in, here's what you need to know about Genshin Impact Theater Mechanicus.

Genshin Impact Theater Mechanicus: How to unlock it 

You'll need Adventure Rank 30 or above and have completed the 'Ritou Escape Plan' Archon quest, which you'll get shortly after arriving in Inazuma. If you meet both of those requirements, you should find the 'Theater Mechanicus' world quest listed in your quest log.

The map marker will take you to the NPC Komakata—she's located just to the northwest of Inazuma City. Speak with her to learn more about the minigame.

How to play Theater Mechanicus 

Theater Mechanicus is essentially a tower defence minigame. Enemies enter the room from one portal and exit through another, and it's your job to do everything you can to stop them. If too many enemies escape, you'll fail the stage.

At the start, you'll be ported to the arena and given a certain amount of time to set up your defences—or Mechanici—to halt the invading enemies. Each type has a specific element or mechanic that you can use to your advantage. Here are the different types:

  • Rippling Reflections: Attacks nearby opponents with Water Cannons that deal 60% ATK as Hydro DMG.
  • Inferno: Attacks opponents with Blazing Sparks that explode on hit, dealing 100% ATK as AoE Pyro DMG.
  • Furious Discharge: Attacks 1 opponent at a time with a Thunder Strike that deals 80% ATK as Electro DMG.
  • Dust Devil: Deals 75% of its ATK as AoE Anemo DMG and knocks enemies back. Can be rotated.
  • Glacial Bloom: Periodically fires a Frost Bullet in a straight line. Deals 50% ATK as Cryo DMG to the first opponent it hits.
  • Crack Shot: Periodically fires an Arrow Shot, dealing 75% ATK as Physical DMG on hit.
  • Tandem Mine: When an opponent passes by, the Tandem Mine explodes, dealing 500% ATK as Pyro DMG to nearby opponents. After its effects have been triggered, this device will be destroyed.
  • Charity: Nearby opponents have their Movement SPD decreased by 20%. When they are defeated, gain 20 extra Veneficus Points. This effect does not stack.
  • Arcanum: Buffs nearby Veneficus Mechanici, increasing their ATK by 50%.
  • Binding: When an opponent passes by, Arcane Mechanicus: Binding explodes, imprisoning one of the opponents it hits for 3s. After its effects have been triggered, this Mechanicus will be destroyed.
  • Banishment: When an opponent approaches it, Arcane Mechanicus: Banishment will knock all opponents within its AoE away from itself. Once its effects have been triggered, it will go on cooldown for 6s.

You'll get to choose the party you go in with—and you can play co-op too—but it's worth noting that you can't actually damage enemies with normal skills—and you won't be able to use your elemental abilities either. But you can use characters' specific elements to set off elemental reactions with the different types of Mechanici you place down, so it's important to think carefully about which characters you want to bring. Amber, for example, works well on the training stage as the default Anemo-powered Mechanici spreads the fire element from her charged bow shot to others, creating the Swirl reaction.

There are ten stages in total, and each has a different layout to consider. You'll use Veneficus Points to place Mechanici, though you can earn more as you defeat enemies. Even so, you're only allowed to place a set number for each stage, so positioning is essential. You can rotate Mechanici that have already been constructed by interacting with them or reclaim some of the points spent if you choose to deconstruct one to place it elsewhere.

As well as using Veneficus Points to construct Mechanici, you'll also need it to draw 'Wonderous Sticks'. These can provide buffs to Mechanici and players, while some will buff enemies for potentially greater rewards. Some stages have bridges that you can retract to take out tougher foes, while others might have enemies coming from multiple locations. The enemies vary, too, so pay attention.

You can gain some extra time if you crowd-control enemies by freezing them in place with a combination of Cryo and Hydro, and Anemo Mechanici work well to push enemies back. But you'll still need to make sure you have the right combination of elemental reactions set up to finish them off.

You're rewarded with experience points after completing each stage, contributing to your Mechanicus Mastery level. Each level increases the number of Veneficus Points you start a stage with, as well as the number of Wondrous Sticks you can use.

Sarah's earliest gaming memories involve playing Jet Set Willy on the ZX Spectrum at a friend's house. These days, and when not writing guides, most of her spare time goes into MMOs—though she's quite partial to JRPGs too. She has spent much of the last decade playing the likes of Star Wars: The Old Republic, TERA, Final Fantasy 14, and World of Warcraft. Sarah has been writing about games for several years and, before joining PC Gamer, freelanced for the likes of TechRadar, GamingBible, and Rock Paper Shotgun. One of her fondest hopes is to one day play through the ending of Final Fantasy X without breaking down into a sobbing heap. She probably has more wolves in Valheim than you.
