The original and best!
Goldeneye, Call of Duty, Battlefield and all the other first person shooters out there owe their existence to Doom, the hardcore blaster that started a genre. With its science fiction/horror theme, bloody combat and some wonderfully over-the-top weapons, Doom set the template for much that followed and is often cited as one of the most influential video games ever. Players find themselves battling through space stations, blasting wave after wave of demonic creatures unleashed from Hell, with no other goal than to send them back where they came from. There are of course numerous weapons to help you out, including chainsaws, chainguns, plasma rifles and the notorious BFG. Ultimate Doom expands on the original's three episodes by adding in a fourth which acts as a bridge between Doom and its sequel. Even today, Doom stands up remarkably well, with simple but immensely satisfying gunplay, responsive controls and a near perfect mix of action and exploration. It is also highly atmospheric, with some chilling sound effects that create a genuinely unsettling mood, and which is supported by the graphically impressive and well designed levels. If all you know of FPS games is Call of Duty or Battlefield, then you owe it to yourself to dig this one out and find out how it all began.
