I'm trying to pass the guards but am having a hard time! I read the walkthroughs but still can't do it! Does anybody have any ideas or can I post my save file and someone just pass this section for me?

which one r u talking about, the one where u hav to push the block and crouch under the beams, cus im having trouble with that one, i think it was right across from the akuda bar

If you're talking about the Alpha Section HQ just across Fountain Square, which requires the star key to enter, you just have to be as stealthy as possible to get past the guards.
