Well apparently there are classes, as I got an achievement for Eliminating enemies with all Gun Classes. But it’s not like the classes we think of. It’s more of a “Play the Way you want” class. Like I have my guy with a lot of “Stamina” (health) on his armor and such, and a Light Machine Gun with a Perk that lets me revive people from a distance, which is a mod I was able to unlock from a certain ability. So technically, I’d be classified as a Medic. I’ve seen some cool combinations like that.
As for Content, there is a lot of content available, but it feels like once you finish it all, there might not be much except for the Dark Zone and Side Missions. You can always go to Situation Boards and get more Missions, but it seems after the main Missions, it might just be grinding levels, and getting your base built. Maybe the Dark Zone too. Haven’t finished the game yet, but I will update once I do.
The Dark Zone is tons harder now, with more encounters with NPCs, and the PvP environment is a bit scarier now, because NPCs actually rush you during an extraction, making it more intense if you have a Trigger-happy team out for your blood, because you jacked their Rogue Friend’s stuff.
