For the next ten weeks, the PlayStation Network will be celebrating exceptional games by discounting selected titles on the PlayStation Store every seven days. This week, Gravity Crash and Everyday Shooter will receive a $5 discount.

As a routine each week, Mike Kebby has released a list of items, that will be released on the EU PlayStation Store. Mike Kebby writes "Things are ramping up in terms of content, and I’m sure there is something that caters to everyone’s tastes in each of the updates that round out the year. We’ll also have a new batch of Special Offers next week to see out the year too, so keep your eyes peeled for those". Notable additions to the EU PS Store include, PixelJunk Shooter, and a fair amount of PSP Minis. The list can be found below.

Namco Bandai has joined up with Timeshift developer Saber Interactive to produce Inversion, a unique third-person shooter that’ll have Isaac Newton turning in his grave.

As police officer Davis Russell, players will be tasked with locating his missing son after an alien species invades Earth and creates a gravitational imbalance; in one district you’ll be walking on solid ground, in another you’ll be scurrying across the ceiling. Conveniently, Russell’s futuristic arsenal features a gravity-manipulating Grappler weapon able to lift, move and throw objects of considerable size, which can be used to shift obstacles, provide cover from gunfire, or (more appealingly) pound extraterrestrial enemies into the ground. Or ceiling.

Saber CEO Matthew Karch comments: 

'We are doing things in Inversion that most people didn't think possible on the current generation of consoles. We can't wait to get Inversion in the hands of gamers.'

Prepare to have your world turned upside-down sometime in 2010.
