Help Finding Space Shooter Tutorial

I need help finding a space shooter tutorial because i am not really to good at coding (but i am kinda learning gradually). I know unity has on but i am not talking about that type of space shooter.

More like This type (found image online) :


So can some one please point me in the direction of some tutorials (and yes i have been looking for some)
Thanks in advance!!!
