AFAIK, you as a player don’t have a level. The numbers on the locations are just a general sense of difficulty. But you can technically take them on whenever you want, and on a one-on-one basis, you’re not at any meaningful disadvantage.

Look closer. The weapon perks are divided into tiers. You “buy” tiers with feltrite. They’re not unlocked with XP or whatever.

And, sure, there’s stuff that unlocks as you build experience with those three partners.

There aren’t levels, to the best of my knowledge, in the sense of “oh, this is a level 7 camp, and I’m level 5, so my weapons are only going to do 60% damage against them”. A goon is a goon is a goon. Your assault rifle (without additional perks, anyway) doesn’t do more damage when you’re at level 14 than it does when you’re at level 3.

I could be mistaken, but I don’t think I am. The difficulty you see at camps and stuff basically reflects what types of enemies there are, how many you have to fight, and maybe what kind of cover and stuff you have to work with. I could maybe believe bad guys at higher level camps are more aggressive or maybe have a wider variety of weapons, but when I was clearing the map out, I’d sometimes go from a level 7 to a level 2, and on an enemy-by-enemy basis, they really didn’t seem any different. I mean, vanilla goons versus the Shrouded, sure, there are differences, but one dude at one camp versus the same type of dude at a different camp at a different difficulty...identical.

There are so many different currencies and skill trees that I forget if there’s a generic level for you as a character, or if the only levels are tied to your three partners.

You get the best vehicle of the game when you level up one of your partners to 10. The colors of the locations on the map correspond to one of your three partners in Project Dagger. Complete the locations of one color until that partner is at 10, and it’ll unlock. You’ll see the levels for each partner on the map menu.
