The first game that comes to mind when playing Inversion is Xbox 360 classic Gears of War.

Much like Epic's masterpiece, Inversion features third-person cover shooting, as well as an invading underground army to contend with.

Playing as Davis Russel, one of two police officers, your world gets tipped upside down following a large-scale attack by people who seem to live underground. See, even the story is similar to Gears...

Inversion starts off well enough; with the first level taking place as the Lutadores (the game's version of Locusts) invade. It's a pretty promising start, as pedestrians go running everywhere, but the game quickly settles into a "shoot-everything-that-moves" approach. It's a pity, as we would've loved to see more chaos of that sort.

The gameplay itself is your run-of-the-mill cover shooter, with your usual variety of shotguns, sniper rifles and assault weapons on offer.

Gunfights are fun though, thanks to satisfying weapons and some destructible cover. However, the AI isn't the best, often opting to stay in place, rhythmically popping their heads up from cover.

But Inversion does have one neat gimmick to make it stand out from the cover-shooter pack – the ability to manipulate gravity thanks to the Gravlink tool. Enemy sniper firing on you from above? Simply make him float and then pick him off. Heavy obstacles blocking your path? Then invert the gravity so it's no longer a problem.

It sounds pretty intriguing, and some of the aspects, like shootouts in areas entirely warped by gravity, stand out. But more often than not, the feature is poorly implemented, feeling tacked on more than anything. Half Life 2 this is not.

The single-player mode will keep you busy for a weekend, but there's also a multiplayer suite around to keep you coming back. However, we struggled to get a few games during our review period - let's hope it isn't dead in the water this soon.

When it comes to graphics, the first thing you'll notice about Inversion is how brown and grey it looks, with lashings of blue and red when you use your Gravlink. Again, the game brings to mind the first Gears of War, but more so because it looks like a first-generation Xbox 360 game.

Character models are serviceable if bland, while environments seem to lack the scope of contemporary games, such as Spec Ops: The Line. 

On the audio front, Inversion doesn't stand out much, with forgettable voice acting chiefly to blame. Nevertheless, it gets the job done anyway.

In fact, "forgettable" seems to be the best word to describe Inversion, doing little to differentiate itself from the bunch.

Unless you're looking to satiate your appetite for any and all cover shooters, give this one a rental first.
