ZERO Sievert News

[p]That's right! We fixed the Steam Deck and Prologue issues we introduced with the latest update (sorry about that...)[/p][p]A massive THANK YOU to everyone who let us know you were experiencing issues and provided extra info on just how they were effecting you. This really helped and allowed us to quickly identify and resolve the issues.

For those wanting the specifics, here's the few notes for this hotfix:[/p]

• [p]Fixed an issue which prevented the game from loading correctly on Steam Deck[/p]
• [p]Fixed an issue where Steam Deck users were unable to use consumables[/p]
• [p]Fixed an issue which caused the Prologue (tutorial) to crash[/p]

[p]These fixes combined should immediately improve the stability and overall experience of the game for you (because who'd have thought being able to complete the tutorial was a good thing...).[/p][p][/p][p]Again, the biggest thank you to all of our players and community for providing insight and being patient while we fix these issues. Being a small dev team, it's no surprise that we encounter these issues from time to time, but your support, especially in providing logs and information on bugs, sharing the game with your friends and leaving Steam reviews to help get the word out all means the world to us.[/p][p][/p][p]We've been trawling Steam reviews, responding and jumping in DMs with players to get extra info and resolve issues, but did you know we have an active Discord? Click the link below and join us over there where we can turn around feedback much faster than on Steam (most people refuse my friend invite as they think I'm a bot :( We even have a channel dedicated to Steam Deck chat! https://discord.gg/DkTTUVF5qs[/p][p][/p][p]We're ever grateful for every positive review we receive and can't explain how happy we are that you along for the ride with us. Thank you.[/p][p][/p][p]- ZERO Sievert Dev Team[/p]

[h2]📖 New Game Events for Modding[/h2]

Trigger your own stories and systems with these new mod-accessible events:

• "enter_hub" ➡️ Called once when the hub room is entered. This means when you start a new game/load a save, or return from a raid.
  
• "enter_raid" ➡️ Called once when the raid is started. Specifically this runs right after you continue past the loading screen.
  
• "exit_train" ➡️ Called once when the player gets off the train during a raid. This is performed immediately after the player position near the train.
  
• "player_spawn" ➡️ Called once when the player spawns into the world. This will occur when you first enter any (Game Maker) room/level.
  
• "player_death" ➡️ Called once when the player dies during raids.
  
• "trade_completed" ➡️ Called whenever the player successfully completes a trade with a trader.
  

Show us what you can do with them.
We also lovingly updated the documentation with all of this and more, don't forget to check it out!
