Glitches I encountered:
-Under map while prone
-Blue tinted screen
-Couldn't aim down sights
-Gun became semi-auto instead of full-auto - Not a glitch you can change the fire rate of your gun by pressing the down on dpad, believe up is turn off torchs or lasers

May be the other way around.
-Couldn't sprint
-The whole area by one of the first plant sites is glitchy as a whole
-Wasn't getting hitmarkers
-Game would freeze
All these things happened to me throughout my first day of playing the Battlefield 3 beta, however I still had a great time and I thought it was a great experience and once those issues are addressed, I think I will buy Battlefield 3
