Two more campaigns for Doom 2, The Plutonia Experiment and TNT: Evilution with 32 levels each. Really difficult and you have to walk around looking for each and every spare bullet you can find.
Here I write what I think about the games I have played. The score is shown as a smiley before the title of the game.
Note about Movies: None of the Youtube movies that i link to are made by me and i include them only to give you a chance to see what the game looks like. Only the text and the smiley score act as my review of the game .
