A boss has been added for level 9, he is a 4 legged robot, you have to shoot each leg twice to make them explode. After destroying all of the legs, the robot is defeated. I made new textures, models and sounds for the fight.

I have changed up the layout of the main hub. Including a giant castle for you to scale,  I think this is much better than the original version.

Finally, you now are forced to to unlock weapons and stages, and can't access to all of them during the beginning of the game.
