PowerLeveling BUG

Over the summer I have been playing Crossfire- CHINESE version which is more updated and newer. There is a leveling bug widely used- I wonder if it should work in the NA version of CrossFire?

What you do is you create a room with these exact settings:

MAP: Columbia EM
MODE: Elimination
ROUNDS: 13

What you do is each person on one team will take a grenade and lob it at their feet and get killed. The round ends and then you repeat this until the other side has won 12 of the rounds. Now the opposite side does exactly what you did- lob grenades at themselves until 12 rounds and then either side can kill themselves again.

The experience is really great and this bug is really fast if you know what you're doing.

（Maybe this discussion should go in the glitch section) But I need people's views on this to see whether it is possible and I need a few people who want to try this out. (ign: [MERCENARY])
