A while back, I decided to play Transformers: War For Cybertron after not playing for a while. Since I had just renewed my Xbox Live Gold membership, I'd thought I'd give the multiplayer a test drive. After 30-45 minutes of playing the multiplayer, I decided it was high time to beat at least half of the campaign, so I went into the second-to-last checkpoint of the fifth chapter of the Decepticon campaign. I had barely played five minutes of it before the screen froze, the only sounds that could be heard were the wildly vibrating controller and the background music constantly jumping. Scared, I took the game out, put it to the side, and haven't played it since, in fear of a repeat of the same incident. Now, I want to know, are there any known glitches in Transformers: War For Cybertron, or what had just occurred happened because of a damaged disc?
