create 3d zombie survival shooter game for pc -- 2

So i want it to be my boyfriend and i at an amusement park but shooting supernatural creatures or zombies haha The goal is to make it across the amusement park and get to the rollercoaster. Once they get to the rollercoaster, they win the level. But the zombies/creatures can also attack and try to kill us if we don’t shoot them first. We have a certain life bar of health So the idea is: you spawn in a map (park) and there are zombies spawning once you kill them all you have to get in the rollercoaster and it gets you to the next level and same again but zombies get harder every time you level up It’ll be a single player, offline game. I need the game to be able to be played with an Xbox controller that’s plugged into the Pc, not a keyboard
