Please create a button mapping within the Unity Input Manager.

I'm trying to run the Demo but the guns don't shoot. I can move and jump but none of the other things work.
The Input Manager says Fire1 is the mouse 0 but it isn't really.

For me everything work well. Did you setup the project?

Yes, updating the buttons fixed it, Thanks
