What a good program to make fps shooter game (like modern warfare )please read the detail?
You don’t really have “programs” that just make games. You can start with an existing engine but that still takes a ton of development work. If you’re really interested though, some of id’s older engines for Quake and the like have had their source code released for people to play with. You could make games with that, but it’ll be a LOT of work, and they won’t be like the modern stuff. Truthfully if you want an engine of modern game level, you’re going to have to start from scratch, which is a huge, huge undertaking that usually involves much more than 1 person.
