well the real last level is about as long as the introduction 1-17 levels so i wouldnt doubt that it could take some 3hrs.. but i managed to fair well under that and got cake. I hope everyone explroed around to find all the hidden markings on the walls and such. another thing.. im playing through hl2 again.. and i just realized how massive this game really is.. seriously, its one big map! i forgot how long this game really is!!! I played a quarter of it when it was on pc, played through it when it was released for the xbox1.. Playing through it again and knowing whats ahead and what to do quickly STILL doesnt make it go through faster.. amazing! I hope ep1 and 2 are just as long How can they cram all this into 9gb?
