MMO? Surely its a team based shooter? But anyways no matter what it is i enjoyed playing it, found it does fall in to the trap of some free to plays in which there is a point it wants you to play too much to gain any sort of reward, depends if you dont mind the grind. Though you dont need to pay for anything, and you can get everything in game. Should transfer well from m&k to controller as well.

I have'nt played it myself, but will be giving it a go

The link says MMO so I went with that, it's free I like tanks sounds good to me.

World of Airplanes was also pretty good, but it's one of those games where if you pay £6 a month then it is slightly less grindy and there are less restrictions.

Anyway it is a brilliant game, I played it for a few years on the PC. There are also some really good Mods for the PC that make it a lot better in terms of the UI and the sounds of the tanks etc, not sure if that will be allowed on the PS4 version.

Playing world of tanks today, well worth downloading, especially when it's free.
