9: Assassin's Creed

Ubisoft knows awesome stealth (Splinter Cell). The company also knows amazing acrobatics (Prince of Persia).

Thankfully, that chocolate and peanut butter mixed together to make the delicious Assassin's Creed. With crazy parkour moves and devastating attacks, Altair has become one of gaming's most revered heroes in quite some time. We can't wait to see who he kills next.

8: Resistance: Fall of Man

Resistance stood out amongst an army of first person shooters by taking the tired World War II formula, and throwing an alien invasion into the mix. As US Army Ranger Sgt Nathan Hale, you were thrown into this inventive scenario with gun in hand, and a nation that needed saving.

With an extensive single-player mode, split-screen co-op, and a fantastically customisable online gameplay, Resistance proved that it wasn't just another launch title, but a whole new form of shooter.

7: MotorStorm

It's been over a year and a half since Motorstorm released, and the brutal slo-mo crashes are still the best-looking in all of gaming. It also doesn't hurt that the game has exceptional gameplay and a wide variety of courses and vehicles.

About the only thing that's missing is split-screen multiplayer, which the sequel should be adding. But for a bargain-basement 'Greatest Hits' price, you can't go wrong with Motorstorm.

6: The Orange Box

The Orange Box included five hit games from the FPS gurus at Valve Software, making this a must-have for any shooter fan. Not only do you get the award-winning Half-Life 2 and the follow-ups Episode One and Two, you also get the butter-smooth online game Team Fortress 2.

But the real jewel of this fantastic collection is Portal, a mind-bending puzzler that every gamer should experience at least once. Armed with one of the coolest weapons ever devised in the Portal Gun, you run through a series of deviously designed levels while the omni-present voice of GlaDOS gently coaxes you onward. Filled with delicious humor and addictive gameplay, Portal is worth the purchase price alone but lucky for you, you have four other amazing games to keep you occupied long after you've discovered the secret of the cake (hint: it's a lie).

5: Call of Duty 4: Modern Warfare

Call of Duty 4 wasn't just another cut-and-dry shooter. In the fourth installment in the popular FPS franchise, the player was sucked into a larger than life story, allowing them to play as both a US Marine or a member of the British SAS while a global conflict ignited. With an astonishingly deep single player mode and an insanely addicting multiplayer mode, Call of Duty 4: Modern Warfare was a turning point in the first person shooter genre.
