Well like wine gets better over the years this game actually started to rot. I am a massive iD software fan but I have to give my honest take. First off compared to Doom the level are bland as ever, It was a nice technical achievement back in the day but it didn't hold up to the test of time, grey floors and ceilings without textures, rectangular walls and the same sized doors, room after room after room.. I started up the game but couldn't pull myself through more then 5 levels, it's just too boring now. The score system with lives are some remnants from the arcade days that just doesn't fit in somehow. The movement is a bit strange and ultimately it lack atmosphere and level design that make other iD games so legendary. How many times did we run through Doom and still and amazed at the level flow and placement of secrets, items and monsters? Same goes for Quake. They never get boring, actually one might say they are becoming better because every once in a while you find something new, like a secret room or a new route or even a rocket jump that makes you skip sections! All in all it was a great game then and its a okay game now that stands in the shadows of greater games. Would only buy this if the price was right.
