Help with glitching

Hi, im new tho MPGH and im new to glitching in combat arms, so i really dont know what most of the people here are doing. Ive heard things about glitch keys lag generators and stuff but i dont know what they are. I also tried the two towers glitch where you go in the corner near the stairs on the top floor but i cant get in. I also tried this on many other glitch sites people said were good but i just cant get in them. Anything anyone can offer for advice or help would be greatly appreciated

You could remover the CHAR_ file. I forget which one it is, but that will help.

You may fall through the map though. xD
