Battlefield 3 beta

I've been playing the beta although i should be studying for exams. The game has many bugs so its a good they allowed it to be an open beta. While playing the beta here is some glitches I found...

• Health packs can break concrete 
• sometimes the grounds swallows you =3
• the AN-94 doesn't make sound when you shoot it sometimes 
• the UMP OWNS in every game its in...every game
• if you go prone in a corner you're f%^&ing invisible and scary
• turn your brightness up so you can see, just saying
• the little robot you unlock in the engineer class puzzles me, someone planted a charge ten times before I realized it was doing it

Fun game, I look forward to playing the full game October 25
