I returned 3 copies from Walmart and GameStop because GOW Ascension would not load up or detect disc in my 120 gb slim.. Crazy idea was the disc drive is going out? But all 47 other games I own detect,load, and play fine.. I turned ps3 on its back held it there disc slot pointed up game disc icon popped up and game loaded!!!! I had to keep it propped up like this every time tho or it would freeze.
boiling the game works, theres a thin layer of wax left over from the manufacturing plant...it doesnt let the ps3 read em correctly. Place the disc in boiling water for like 15 secs, make sure its COMPLETELY dry before placing in ps3..voila, ur welcome
