Nothing special, just made all kinds of grinding this game has to offer: region battles, infinite respawning side missions, forts/locations clearing on previously recorded places, animals hunting, ship battles. All this was made off the record.
Hey Zevik, since I'm new to COD: Infinite Warfare, i'm gonna do Specialist and Yolo, but what does it do? Are there same. Also, is it harder than Veteran?
YOLO=You Only Live Once Literally, after the death, the whole game is restarted. Specialist = YOLO, only difference is that the game isn't restarted after death. Of course as a PC master race gamers, we have the option to store manually the save files of the game in separate folder after each successful mission and restore it in case we die in the game and the game restarts. That's how I did my walkthrough, but shhh... don't tell anyone :)
