I went outside for the first time today. Working at home is an easy way to get a bad case of couchlock, so I like to try and get out for little 15 minute breaks when I can.

Today was a bit different. I downloaded and installed a game some buddies of mine are raving about on Facebook: Ingress.

I launched the app, followed the instructions, and was hooked. What started as a 15 minute walk to try out a new mobile game became a 45-minute obsession as I roamed my neighborhood, looking for portals to hack, collecting XMP particles to power my technological takeover, and finding a little feature of my ‘hood I’d never known about before.

Want to get obsessed about a new game? Want to maybe get in a little better shape? Be sure to download Ingress and see what everyone’s talking about.

Mark Smith’s Spell Quest: Grimm’s Journey is this week’s iOS Game of the Week, and it’s a fun one.

You’ll need to spell words to move Grimm from left to right, with longer words causing more damage to the baddies you encounter. You’ll pull letter tiles from a grid below, and some tiles will give you power ups, others will poison you. It’s a fun mix.

Check out our video below for some gameplay footage.

Gamestop-owned Kongregate games has gotten into the mobile gaming space recently, and the latest published by the online gaming portal, Sheep Happens, has a lot going for it.

Sheep Happens throws just about everything at players, like wacky characters, missions to complete, and plenty of power-ups to earn and/or purchase. While the humor is a bit over the top, the gameplay finds a pretty decent balance between difficult and engaging gameplay fairly early on. For players willing to spend some time and/or a little bit of cash, the later game ramps up nicely, making Sheep Happens a nice diversion for those of us who haven’t gotten sick of the endless runner.

Most days, you won’t hear us talk too much about a gaming genre that’s been beaten to death with a large stick, but upcoming Puzzle Knights is an exception to that rule, what with it’s interesting blend of, yes, matching colors, but also tactical strategy, light RPG elements, and online arena battles.

The game is expected to release sometime in the first or second week of September, so keep your eyes on this one. It’s exclusive to iOS, but will let you connect via Facebook to battle your FB friends.

Champs Battlegrounds is an odd mashup of strategy board gaming and multiplayer online battle arena (MOBA) mechanics. Quark Games has created something compelling, though, with this free-to-play iOS game, available on your iPad or iPhone.

Apple spotlights a new iOS app each week as a special pick: the App of the Week. Last week, it was a gorgeously designed alarm clock, Rise, that caught Apple’s editorial fancy.

This week, it’s Namco Bandai’s Doodle Fit 2: Around the World, a delightfully drawn puzzle game that’s sure to keep you frustrated yet coming back for more with its maddeningly simple concept.

Video games are often praised right out of the gate due to their amazing graphical fidelity and smooth animation. A less visible but equally important feature of any game, especially in the realm of first-person shooters, is the control scheme.

DeNA / Mobage’s The Drowning, out today as a universal iOS app, has seemingly nailed both of these things in a game that’s taking the iOS gaming world by storm. And perhaps shotgun.

This frantic, wacky 2D endless runner from Illinois-based development studio High Voltage Games (Zoombies, The Conduit HD) has just been chosen as the iTunes App Store’s Free App of the Week. To celebrate, Le Vamp is now completely free to download and try out for the next few days.

Hurry, though, the special offer only lasts through August 1 at 11 pm Central US time.
