|Octo Valley - Final world Screenshots:|
The level designs in this game are so good. I never would've expected to get some actual legit 3D platforming in a multiplayer shooter.
And then the final boss... omg this boss is inkredible. It has like 10 phases, and it takes place on a platforming stage where you progress into the next phase by moving across the platforms after you push the boss back by doing some damage to him. Each phase gets more and more intense, and by the end you only have these tiny little platforms to stand on while dodging a ton of projectiles and a huge laser beam that he shoots out, and you have to do all that while also hitting a certain projectile back and forth like a tennis ball to damage him This boss took me a few game overs before I got good enough to beat him, it felt really satisfying.
After you beat the story mode, if you go back into Octo Valley there's some extra dialog, and of course you can still access every level, just in case you haven't found all the research notes yet.
