Sweet! but add more

This game is amazing! But it would be far superior if it even had one of these four things
-MULTIPLAYER.
-OTHER GUNS, such as a machine gun, pistol, grenades, and a rocket launcher.
-CO-OP- or at least a way to play with friends online.
-DIFFRENT THINGS TO SHOOT- such as a boss demon that you can take down or hordes of zombies.

-Thank you for reading my review, hopefully you will add all of these suggestions in the sequel! :)
