The term “out of this world” doesn’t even begin to cover how amazing this week’s giveaway is. Seriously, we’ve got so many games up for grabs I couldn’t even squeeze ’em all into the above title without making it ridiculously, unretweetably long! Joining heavy-hitters MASS EFFECT™ INFILTRATOR, Kids vs Goblins, and Adventure Bar Story in the digital prize-bag this time ’round are a dizzying array of must-have indie games like (deep breath) BeyondDead, Mystery of the Japanese Werewolf, Four Hatsand Save the Monster. Phew!

Here’s a little more info on each and every game you can win this week –

MASS EFFECT™ INFILTRATOR: It’s a mobile version of Mass Effect brought to stunning life by IronMonkey Studios, the crazy-talented team who gave us one of iOS’ most brilliant games to date, Dead Space; I mean, what’s not to love? This portable companion piece to smash-hit console trilogy features an all-new, original storyline set in the Mass Effect universe, absolutely jaw-dropping graphics, and intuitive swipe-and-tap controls that make the game’s fast-paced combat a slick affair. We’re giving away one copy of this essential title.

Kids vs Goblins: Having already catered to hardcore RPG fans with the likes of Rimelands: Hammer of Thor and Aralon, Crescent Moon turn their attention to getting new players hooked on the genre. Their latest, the Stolen Couch Games developed Kids vs Goblins, is a charming and accessible introduction to role-playing games set in a whimsical fairytale world of magical creatures, monsters and Maurice Sendak-esque heroes.

*When entering, please bear in mind Kids vs Goblins is so gosh-darn magical, at present, it’s only compatible with higher-specced iDevices like the iPhone 4S and iPad 2.

Adventure Bar Story: When you can level up in a JRPG by eating pizza and drinking beer, you know it’s special. By the sound of our review ZigZaGame’s and Rideon’s debut iOS RPG – which packs in dozens of gameplay hours – should be enough to fill even the hungriest genre fan. If that describes you, you’ll want to enter for a chance to win the extra promo code the publisher was kind enough to send our way!

BeyondDead: My, Monster Robot Studios games are becoming a regular fixture in our weekly contests, aren’t they? Now that this title’s somewhat unwieldy controls — our main gripe with the game when we reviewed it recently — have been given some much needed attention in the latest update I’ve got no qualms about labelling BeyondDead a must-have for fans of Metroid-style side-scrolling adventures. Thanks to our good buddy Ash Jackson at Monster Robot Studios, we’re giving away five promo codes!

Mystery of the Japanese Werewolf: Another Metroid-esque sidescroller that just benefited from a humongous update is Daniel Novais’ rib-tickling homage to the NES era, Mystery of the Japanese Werewolf. Check out our full review of the game here and enter to win one of five codes courtesy of the dev.

Save the Monster: This stealth-based puzzler from ScottiStudios and CorpDesign is perfectly adorable and fiendishly addictive! Intuitive controls, crisp and colorful visuals, quirky characters, and heaps of levels all add up to a monster-sized helping of fun. Thanks to our friends at ScottiStudios, we’ve got two promo codes up for grabs.

Four Hats: We called Taco Graveyard’s App Store debut an “exhilarating and raucously entertaining sidescrolling caper” in our recent review of the game, and it’s only gotten bigger and better since then. The freshly updated Four Hats features a new endless mode for each song and snazzy ‘quick touch’ controls, along with a ton more tweaks and improvements. Thanks to Taco Graveyard, we’ve got five codes to give away!
