confuzzled... Can you explain why it only works on Dustworld ( Its a great invention i just want to know ).
The co?rds used in the button in this trainer only work for this map. If you try them in another map, you'll probably teleport outside the map, which will get you kicked for #148 (if I remember correctly).
Or when using in unprotected servers, you'll probably just fall down and get yourself killed.
If you are lucky in some maps you won't teleport outside the map using this trainer, but don't expect to teleport to useful places.
