ARC Raiders players on PC can use a trick to manipulate the game. They do this by changing their system date while in the game, forcing the state forward and tricking the game’s internal calendar. By doing this, some users have revealed future map conditions, trials, and other additions.
For the most part, yes. Not a guarantee but I played like ~50 some hours over winter break, all solo, all peaceful. Ended with like 3 deaths due to players.
It is, however, not smart enough to separate solo and party behavior. So if you play aggressive with your buddies but peaceful solo, there is a very painful transition period.
