While adding physical controls instantly improves almost any mobile game, no one wants to carry around a big, bulky control pad all day. But it’s unlikely you’ll have any complaints about taking the iMpulse with you everywhere you go, because it’s so small it fits on your keyring — and it’s compatible with both Android and iOS devices.

Australian-based developer Halfbrick is at it again, with free-to-play Colossatron: Massive World Threat, now available around the globe.

You’ll take on the role of the humungous mechanical robot Colossatron on your quest to utterly destroy city after city, using various colored robotic modules to give your wanton destruction just a little extra oomph.

Yeah, color-matching doesn’t sound that fun, but this one? It really is.

Dead Trigger 2, the sequel to heavily-downloaded hit zombie game, Dead Trigger, burst onto Google Play and the App Store late Wednesday night, bringing next-level graphics and gameplay to devices in your very pocket.

This first-person shooter has an all new touch control scheme that was created, says the developer, Madfinger Games, specifically for casual gamers. You’ll be able to use the virtual joystick, of course, and Android players can use supported game controllers. What’s interesting, however, is the new casual-gamer-style touch control scheme.

You’ll immerse yourself into a world where the humans are fighting the zombies, like you do. The game itself, however, is played out in real time on a global scale.

Seminal 1990s tabletop role-playing game, Shadowrun, has recently come to the digital domain, originally with a version of Shadowrun Returns for the Mac, PC, and Linux platforms. Cult of Mac gave the game a stellar review, calling it a “fully realized tabletop to digital RPG conversion.” Say that five times fast.

Now the game is finally on tablets, both of the Android and iOS variety, and the buzz is that it’s a note-for-note port of the desktop game, minus the campaign editor. That’s a lot of game to smoosh into a tablet.

Dragon Age and its sequel (cleverly named Dragon Age 2) have provided PC and console gamers with deep, solid role playing set in an original fantasy world with engaging characters and a wide array of choices to make in storytelling and combat.

While the overarching story is what makes these games work so very well, the combat system, especially in the first game, is unique and compelling to play.

That makes the announcement of a new spinoff of the well-reviewed series, coming to Google Play and iTunes this fall, pretty darn spiffy, as Heroes of Dragon Age seems to focus solely on combat.
