I was a tween/teen when the first DOOM came out, and played every DOOM since. The amazing thing about this version is that it (surprisingly) does manage to both pay homage to the original while also updating the game play to be a modern shooter. There is a single player campaign, with a fairly weak and uninspiring story (much like other DOOMs), but there is a story. The game play has the classic fast and simple appeal of the original – never stand still, run over things to pick them up, blue health/green armour/multiple types of power up and ammo. There's still ‘secrets’ to be found too. Glory kills, combat challenges, weapon upgrades etc. All add something new. The graphics are great and the setting on mars works well with the Zombie theme. I would say I found it shorter than I expected (took me around 20 hours to complete the campaign on ‘hurt me plenty’, and I'm a pretty average gamer), and the multiplayer while not bad is a meh (I suck anyway). So it's not a reboot, or a reimagining. It's a modern update of the original, done well. If you liked the original DOOM then you should like this, if not, it's probably not for you. If you never played original DOOM – well you might be missing the nostalgia factor, but it should still be fun given the fast paced action makes it fairly different from a lot of today's FPSs which are mostly cover based.
