Just picked this up from the clearance bin for $6.
It includes the original Doom games from the 90s.
I played through 'The Earth Base', which is level one of Doom 2...
Time: ...par for time is 30 seconds.
It took me over an hour of running in circles looking for doors. I finally cheated and watched a play through on YouTube.
Meanwhile, I'm kicking serious ass in Doom 3. How can an ancient legacy game be so much more dificult.
Still, loads of fun.
