Let's figure out what actually happens in this game...
I've had a lot of trouble understanding the mechanics that aren't explicitly explained in the tutorial or a couple games of practice play, so I decided to collect all the content updates Project Winter ever had with a list of the lasting content additions so that it can be easily skimmed.
Before going through any of this, I recommend having already gone through the in-game tutorial. Then the Beginner's Guide and Navigation on the wiki.
All Links
Here's the collection of wiki links that end up getting referenced in the Content Updates, so reading all of these should give the current state of the game, more or less.
- Survivors, Traitors, Additional Roles, Ghosts
- Objectives, Bonus Objectives
- Buildings: Laboratory
- Items: Energy Drink
- Weapons: Poison
- Global Events, Traitor Airdrop
- Cooking
