Official update history
Hi everyone!
Yesterday we released the Rebalanced update and it looks like you're all really enjoying it! If you haven't read the update covering what it contains, read it below.
[dynamiclink href="https://store.steampowered.com/news/app/3772810/view/540007781835473175?l=english"]We've adjusted some small things to make the balance even better, read the patch notes below.
Changed the loot stat contribution text to always show "previous stat -> new stat", even in the equipped view, whereas before it was "new stat -> previous stat".
Fixed a bug where the stat values for the Firm Grip and Shadow Strike loot were mixed up.
Wizardry loot % Damage Reduction: -70% -> -40%.
Dragonborn loot % Damage Reduction: -55% -> -40%.
Added the "Precise Collisions" setting. In the previous update, we made projectiles interpolate to have greater accuracy, but this came at the cost of worsened performance on lower-end devices. By default this setting is off, but if you turn it on your high-speed projectiles will no longer skip over enemies.
Fixed a bug that caused loot with higher than 100% stat effects to display incorrectly in the loot view.
Fixed a bug that caused the achievement for unlocking all weapons to not take into account the 2 newly added weapons in the Critical Update.
Fixed a bug where the mastery achievements for the 2 newly added weapons in the Critical Update didn't display their text properly in some languages.
[dynamiclink href="https://store.steampowered.com/bundle/67188/Desktop_Defender__Card_Corner/"]As always, if you're enjoying the game, I would REALLY appreciate it if you reviewed it. It's the best thing you can do to support the game if you're enjoying it!
Thanks again, and keep on enjoying Desktop Defender!
