Another week of mobile game releases is at hand. More importantly, another week of mobile game discounts is at hand! The deals listed below don't have a listed expiration date, so grab while the grabbin's good.

On sale: Bastion - The "almost too awesome for its own good" RPG Bastion is on sale! You can grab the iOS version of the game for just under a buck, which we don't need to tell you is an amazing price. You take on the role of "the Kid", a white-haired lad who wakes up one morning to discover the rest of the world has literally collapsed away, but finds paths rise up beneath his feet as he travels through a hostile realm.

New to iOS: LIMBO - The game that has nothing to do with the party game but everything to do with the other meaning, Playdead's phenomenal downloadable game LIMBO has just shimmied its way over to iOS devices. LIMBO is similar to games like Another World, where realistic physics take a front seat to exaggerated leaps and fantastic feats of physical prowess. You have a modest jumping ability, can hang on to ledges, ropes and the like, and will be, er, "subjected to" one or two other temporary skills as the game progresses. It's not about what you can do, it's about figuring out how to navigate the strange world using your limited set of moves. The touch controls work surprisingly well with a slow-speed platformer of this nature. (LIMBO review and download)

New to Android: The Silent Age - A runaway favorite mobile adventure game, The Silent Age has just hopped out of iOS territory and landed on Android devices. It's the early 1970s and Joe has a pretty crummy job as a janitor in a large, faceless government building. One day the management calls him in for a talk. It looks like Joe is getting a promotion! And by promotion we mean Joe will now be cleaning the sub-basement laboratories in addition to his normal duties. New keycard in hand, Joe heads down the elevator, only to discover drops of blood and a dying man who claims to be from the future. Promotion, indeed. (The Silent Age review and download)

On sale: Fieldrunners 2 - In the mood for one of THE best tower defense games on any mobile device? Fieldrunners 2 is on sale for a very limited time, discounting both the standard and the HD versions. Fieldrunners 2 pits you against wave after wave of fieldrunners, disposable enemies who crowd the level trying to make it across the screen. By buying and placing towers with different abilities, you can slow and eventually halt their progress, upgrading and deploying more units when the enemy creeps bump up their game.
