April 14, 2010 – Calculator Games today announced that their sci-fi action adventure game, Giant Leap, is now available exclusively for iPhone, iPod Touch and iPad. Giant Leap is the largest action adventure game available on the App Store. In it, players must stop a horde of invading aliens before they reach Earth.

In Giant Leap, the player takes the role of Hero, the sole survivor of an alien attack on an Earth spaceship. They will then have to use up to 5 different weapons to blast their way through enemy forces across 60 levels and a fleet of spacecraft.

“The game is also very story driven,” said Tom Harvey, founder of Calculator Games. “There are lots of twists and turns, with the truth about the invaders only revealed after completing all 60 levels. It’s epic.” Detailed statistics about the player’s performance on each level are recorded, so there’s plenty of replay value for players chasing a perfect score.

Giant Leap is now available for $5.99 in the U.S. and is priced accordingly in other regions. Giant Leap is available world-wide from Apple’s App Store for iPhone, iPod Touch and iPad, or by visiting www.giantleapgame.com.

Calculator Games, an independent video games studio based out of Melbourne, Australia, was formed in 2009 by Tom Harvey.
