I saw something about that. It has destructible environments and some construction mechanics right? Are there specific classes/loadouts that can construct?
Yes! There are a few classes like Medic and Marksman which are pretty similar to those in Battlefield.
In terms of loadout, weapon customization is pretty in-depth. There are a lot of weapons and you can change the scope, muzzle, underbarrel, magazine and more. Take a look at this image.
Something great this game does is that you can’t just slap a long range scope on an assault rifle and expect it to be a long range weapon. Controlling recoil is really hard and you aren’t entirely accurate when scoped in, which is a breath of fresh air compared to some others in the genre.
