Top-down shooter?

Hey guys, remember me?

One of my friends and I want to make a top-down shooter. I’m trying to figure out what program we could use to make it. RPG Maker is the only thing I can think of, so any help would be awesome.

Also, do any of you know an example of a horror game with a similar perspective?

Top down… That’s when the camera is directly above the character right? If so, then I have an engine that I designed specifically for this kind of request.
