I found a really, REALLY good XP glitch with this to rank up super fast
1) Turn this hack on
2) Go on capture the flag and pick up the enemy flag (obviously its easy to pick it up, you are god and invisible )
3) Take it back to where your teams flag is (but don't actually walk on the flag)
4) Before you capture it, change team (So you are basically capturing your own new teams flag)
5) Now walk on the flag and it says you picked up the flag like 10 times a second and you get 100xp each time so you rank up in like 15 seconds XD
