Please don't put in mega micro-transactions. You can have some payments that don't effect main gameplay, but please don't turn into a money grub like many other games like this. I can just say most that try to do something of that like lose a lot of their population.
This game needs a mini gun all great shooters have a mini-gun. Also please add character customization like reducing your health but being able to move faster.
please make it so you can only hold 4 weapons at a time so it doesn't take forever to toggle through them and so you don't have one person that just murders you with every weapon
