Half Life 2 (2004)
Fifteen years after the first Half Life, the crowbar-wielding theoretical physicist returns to join the resistance against the tyrannical Combine rulers. Winning 39 game of the year gongs and numerous game of the decade accolades, this is a must-play for any FPS fan.
Unreal Tournament (1999)
Unreal Tournament focused primarily on head to head player and bot deathmatches where the AI could be set anywhere between novice and godlike. Classic battles such as team deathmatch and capture the flag ensured that a fully blown frag-fest was always on the cards.
The plot of a space marine fighting demons from Hell on Mars couldn’t get much manlier if it tried but – story aside – Doom is also undeniably considered to have been an FPS trailblazer, having pioneered immersive 3D graphics, networked gaming and bespoke mods.
Metroid Prime (2002)
The first 3D instalment in the legendary Metroid series sees an adventurous shooter in which you play Samus Aran, a female bounty hunter kitted out with a hi-tech power suit in which she must solve puzzles and blast down foes in order to progress through the levels.
If your gaming rig could run Crysis at max settings upon its release chances are it was a quantum computer. Eye-watering visuals enhanced the sheer awesomeness of your advanced nano-suit which offered super strength, lightning speed, armour and invisibility.
