Currently I'm building a topdown game where you and your team build a fortress around a core which keeps your team alive. Once the round starts, you fight to the death and upgrade your fortress throughout the round.
As the game is supposed to have a hardcore CS:GO feel, I want to add classes, weapons, and vehicles, but I really want to give it a good feel.
So please, give me your opinions, I really want to make this an enjoyable game.
