Shooting Game

I want you to build the project on Unity, so i can customize it later my self, here is a simple drawing i made ?looking at the game from above. i hope it explains it, imagine Red being player 1 and Blue being player 2, They look at each other in FPV, they can move Left and right but not backward or forward, they cant turn their head and look right or left, they only look straight, and they shoot at each other until one of them is dead. I just want you to make it on Unity As a base for me to work on and add what i want later on, As i anted it to be later on A game for Mobile
