Game isn't just Free to play?
After playing on PC for the first 5 months or so, I started taking the game with me on my mobile to get in a few extra fights over lunch break.
Did you know, the mobile has an icon in the shop to purchase months packs for bonuses.
WOW, not sure I would buy them, but would have been nice to see those on PC, or have had a link to a website with info or an explanation as to why only mobile has that option.
