The point is to make the strongest weapon, so don't complain if someone has a better weapon. You will die a lot, and you will get a lot of kills. If you can't get any kills and just die and die and die it means you are just bad at the game and need to practice. It takes skill. You need to dodge, be strategic, figure out what the other players and using and counter it.
I have a beta key, and it's a lot of fun.
