Here's some of the info and screenshots for the new quest system. Looks like new grunts too that will have weapons now, which defo adds a new dimension to the gameplay.
Here's the developer stream too that goes into better detail on what's coming in:
Seems to be replacing daily/weekly challenges so definitely a very good first step into adding objectives to when you are playing each round. Hopefully they can expand on these Quests to eventually have multiple step quests with a big reward at the end.
This game still has a great intense feel to it.
