I really enjoy it. Some of the progression is a bit annoying. Basically, there are extra upgrades to weapons called overclocks that range from weapon stat changes to full blown changing how the weapon works. However, which overclock you get is up to RNG on multiple fronts.
That said, I really enjoy the gameplay loop. The gunplay is satisfying, and there's decent enemy/hazard variety due to the procedural generation aspect. Folks range from quiet co op to pretty friendly chatter. You'll run into some bad eggs, as with any other multidoods game.
