Looking for a survival game similar to Solomon's Boneyard

[kultrva]

I recently discovered Solomon's Keep and Solomon's Boneyard and have been having a lot of fun with both of them. I especially like the gameplay in SB and it is quickly becoming my favorite iPhone game.

So, I was wondering if there are any other games on the App Store similar to SB in terms of gameplay. I'm looking for a game in which your survival depends on properly building your character and customization is deep.

Price is not an issue, but I would like to avoid freemium games. Any suggestions would be more than welcome. Thanks.
