Another feature you can add to the game is customization of not only weapons, but vehicles too. You can maybe use the same principal as to Insurgency uses, like the point system. Different attachments cost different amounts of points. You can add things like Suppressors, flashlights, lasers sights, holos, red dots, grips, launchers and all sorts of things you can think of. The way you can acumulate points is by capturing positions, taking out enemies, or healing one of your teammates. This would be amazing to see on the day it comes out.
