Bounty Hunter Black Dawn is on sale for the weekend for only 99 cents.
From what I've played of it so far, yes it is indeed IAP based as far as in game currency is concerned, but it looks like you can get mithril through quests (albeit very rarely). Whether you get enough mithril through quests to unlock all the important items like inventory slots, or if you can do repeatable quests that have mithril as a reward, is left until I get later in the game. As far as gameplay is concerned, it's great. The controls are good and it runs really great on my ASUS TF300T. The graphics aren't the best, but they are definitely far from the worst. If this game is as much like Borderlands as it aims to be, I can see myself playing this for quite a while. At $2.99, the price stings, given the IAP restrictions. At 99¢, it certainly wouldn't hurt to try, and it is definitely worth it.
