I want this game to play

So I got a bluetooth controller as a gift but as I was looking for keymappers, either they were not free or they aren't working as i would like them. And I would really like to use it for some games that do not have "built-in" controller support, but because they don't have that much buttons they would be easily mappable. Thank for the replies in advance!

Ive had some trouble finding good fps games with full controller support. Ove played games like ShsdowGun Legends or Battle Prime, but I'm constantly running into games like Special Forces Group 2, where I can only run and look around. Please give me some good games!
