nice ! doom 1 and 2 in one cd . that be a very creative idea , you get over 50 level from ultimate doom and doom 2 . many of you maybe wonder if the level look the same as the pc . yes they do ! they look exactly the same as the pc . the only difference be the enemy for example you will see monster that be not in the pc ultimate doom in the PSX version monster such as the chaingunner soldier , mancubus , arancnoton , revenant , pain elemental and hell knight . in ultimate doom for pc those monster be not there , they be only in doom 2 for pc . but the psx version of ultimate doom you will see those monster when you put the game on Hurt I plenty or Ultra violence . the only complaint be that i think the archville be miss from both game , and i have not see the spider mastermind . i think you may find he in Threshold of pain -lrb- last level in ultimate doom -rrb- . another thing be the pc music for the level be take out , instead they put slow scary music for the level . this be a must buy for any doom fan i buy my copy recently !
