In this video I demonstrate the customization of your weapons and right after I show the current version of the gameplay. This is right now pretty much "what you see is what you get" for the initial EA release, but balance changes or overall gameplay improvements will happen over the course of the entire Early Access phase.
Please tell me what you think and come to the discussion boards and I would be happy to see you there :)
