Monster Sanctuary – Ver. ??? (The Forgotten World Update)

  • Release date: June 24th 2022 (North America, Europe, Japan)
  • Patch notes:
A New Area  
  • Become the first keeper in history to discover the Forgotten World, and its secrets. Delve deep into the lush environments of the Forgotten World, and make use of your companion’s abilities to explore what will be the most expansive area of the game to date!


New Monsters  
  • Encounter 9 new, ancient Monsters that were thought to be long extinct as you venture into The Forgotten World – and one new optional Champion Monster! Continue to push your team building skills to the limits, with over 200,000 Monster Team combinations.  
New Game Modes  

Take advantage of 3 new game modes!  

  • Randomizer
    • All Monsters in game are randomly swapped around! Randomizer adds infinite replay ability options to Monster Sanctuary. Once activated, this game mode cannot be deactivated. 
  • Permadeath
    • Once your Monster is knocked out in combat, it is permanently defeated. There is no way to revive them (except for Phoenix Affinity and Charged Rebirth). You can still use the exploration abilities of a defeated Monster. As soon as all of your Monsters are defeated, Permadeath will be disabled and all of your Monsters will be usable again!
  • Bravery
    • This mode will allow you to play with a limited selection of Monsters to test your team building skills! You will start with 3 random Monsters. In each area, you will gain one new random egg from a treasure chest found nearby the entrance to the area. You cannot gain any other Monster eggs through any other means, except for story events.

All of them can be combined with each other and New Game+. The existing difficulty modes (Casual, Normal, Master) will also work with these new game modes! These are not recommended for beginners. 


New Skills  
  • Not only do the 10 new Monsters come with new skills, but the skill trees of all Monsters have been revamped with new skill nodes!  
New Legendary Keepers  
  • Discover new legendary keepers to battle and defeat in tactical 3v3 combat!  
And More..!  
  • QoL Changes  
  • 13 New Equipment Items  
  • Level Cap Increase  
  • Additional notes: as this update was released on Nintendo Switch nearly a week earlier than initially scheduled (June 30th), the developers kindly ask Nintendo Switch players to please refrain from spoiling the experience for players on other platforms!

Monster Sanctuary – Ver. 1.3 (Counter Attack Update)

  • Release date: December 13th 2021 (North America, Europe, Japan)
  • Patch notes:
  • adds Brazilian Portuguese translation
  • Multiple Egg Donating
    • To make your life as a Keeper a little easier, we added the possibility to donate multiple eggs at once to the Monster Army. It is an additional option in the Monster Army menu and should make the process of donating eggs way faster for you.
  • Improved L/R switching Monster behavior in menus
    • This feature makes managing your inactive Monsters easier! When selecting an inactive Monster first, the game will cycle through inactive and active Monsters. If selecting an active Monster first, the game will only cycle through active Monsters like you know it from before. You can also switch Monsters in the feed menu and monster consumables menu now using L/R buttons on gamepad or a/d on keyboard.
  • New Skills Added: Counter Attack + Sidekick Support
    • Minitaur got some love in this update with the new skill Counter Attack, enabling a powerful revenge! Vodinoy also gains Counter Attack, see below for detailed balancing changes.
    • Sidekick Support is a new Aura making full sidekick teams more viable or allowing Monsters that don’t attack that often to benefit from Sidekick buffs. Dodo, Changeling and Dracozul gained this new skill. Check the balancing changes below for more details.

Monster Sanctuary – Ver. ???

  • Release date: April 20th 2021 (North America, Europe, Japan)
  • Patch notes:
New Game Plus
The first of the two big new features coming to Monster Sanctuary: New Game Plus mode! This mode is unlocked once you have completed the main story content of the game at least once. When you choose NewGame+ from the starting menu, you have to select any of your existing save games – this will determine the extra Monsters and items available to you at the start. You can then start your new save file on the same save slot or on any other save slot.

Here are the full details of New Game Plus:

  • All Monsters and many items from the chosen save file will be transferred to your new save file.
  • Monsters are reset to Level 1, but keep their Shift.
  • Equipment upgrades are removed.
  • Items that are not carried over: Crystal Shards, Craft Materials, Food, Key/Story Items, Level 40 Badges, Craft & Reward Boxes, Battle Items. These items are converted to gold on the new save file.
  • Inactive Monsters level up with your active ones until they reach their level from the previous save file.
  • Explore abilities can’t be used until you encounter Monsters which can use them.
  • Similarly, you can only donate Monsters and eggs to the army which you have already encountered.
  • Some tutorial texts are skipped.
Casual & Master difficulty modes

We are adding two new difficulty modes to Monster Sanctuary (with the current difficulty of the game taking the role of the “Normal” difficulty that is chosen by default). They are called “Casual” and “Master” mode.

Here are the details of how these two new modes work:

  • On Casual, wild Monsters have less health & do less damage. In Keeper Encounters, enemy Monster equipment upgrade level is reduced by 1.
  • On Master, wild Monsters have more health, do more damage, and have many additional skills. In Keeper Encounters, enemy Monster equipment upgrade level is increased by 1.
  • The difficulty can be changed at any time by going to the options menu. It can be changed mid-game.

The new Casual mode aims to alleviate the difficulty curve of our game. However, it’s only a slight decrease in difficulty, which means that players will still need to engage with our skill systems and think about their strategy in order to succeed.

The new Master mode was primarily designed with New Game Plus in mind. It is balanced towards providing veteran players, who have loads of additional options available to them thanks to NG+, a new, harder challenge. While it is technically possible to beat the game on Master mode with a regular save file, we highly recommend using this mode in conjunction with New Game Plus (preferably using an optimized team of six Shifted Monsters).

New PVP Matchmaking

This update also comes with a variety of changes aimed towards making the PVP mode more enjoyable! For one, it comes with a new

PVP Matchmaking system. Here are the nitty-gritty details of how the new matchmaking works:
  • The matchmaking takes the levelof your 3 highest Monsters in the party into consideration (to prevent the potential abuse of having a low level backline).
  • It also takes into consideration the average equipment upgrade levelof those Monsters.
  • Outside of a certain level range (based on Monster level + equipment level), players are not able to match.
  • The matchmaking also takes your PVP rating into account.
  • Initially, the matchmaking will only let players within a certain rating range match against each other. After a certain time in queue, you are put into “extended search”, allowing you to match against others who are also in “extended search”.
  • Players who have a rating of 1300 or above start in “extended search” by default (to prevent higher ranks of the ladder of not finding opponents).
  • You’re also able to manually configure when your game goes into “extended search” (instantly/30sec/1min/2min/3min/5min/never).
New PVP Season

With this first update patch, we’ll also start a new PVP Season in Monster Sanctuary. This means that all players are starting in Bronze league again, which will allow you to once again get rewards for ascending to the higher PVP leagues.

This update features many balancing changes of Monsters, skill trees, and skills – almost all of which were made explicitly with the PVP meta in mind. We hope that these changes will shake up the current team compositions and open up new competitive options.
