WIshing there would be something as good as this for IOS. For fans of dungeon crawlers, this right here might be the king. At least, I think it is for the Android platform. This is 1st person dungeon crawling at its finest, and the dev has been constantly updating it. It used to have 2D sprites for enemies and now it's full 3D. Best part? Randomized dungeons and a very good loot system. 10/10 on this one.
Oh yeah Deadly Dungeons is a very very nice dungeon crawler. One of the best I have played on both Android and iOS. Since yesterday there is one on iOS that is good too : Coldfire Keep.
