If you are a tower defense game fan then you have most definitely at least heard of Fieldrunners. It is the classic and most popular tower defense game on iOS and Android. Bla1ze at CrackBerry noticed it drop in BlackBerry World earlier today and I had a chance to try it out on a friends device. The odd part is that the game was requiring OS 10.2 which is not even available yet. On the other hand it seems to be native and not an Android port which is slick!
Sadly it seems like either Subatomic Studios or BlackBerry pulled the game shortly thereafter even after some picked it up for $2.99. Hopefully it comes back shortly!
