Not as retro as usual on my Saturday posts, Doom 3 is almost 15 years old. It was released in August 2004 on Windows/PC. I used to play this on the Xbox 360 back in the day.
Doom 3 is not a sequel but a reboot of the series. You play an anonymous marine who is dispatched to Mars in the year 2145. The Union Aerospace Corporation (UAC) set up a research facility for developing new weapons and teleportation. Accidentally they opened up a gateway to hell. Something is very wrong on Mars.
You can finish the complete game in about 9 hours. The video below is a complete walkthrough:
Of course, you can play it online. It is the demo version though, but it is playable enough for an hour of fun.
