Elasto Mania II External Packs
you can download an official level pack made by Csaba. This pack
has 15 levels. The numbers in the names were given randomly, the
increasing numbers don't mean they are getting more and more difficult
for example. Csaba has more levels which he will release in more level
packs in the near future.
You can play on these levels by copying the files in the pack with the extension of '.lev' to the directory where the game keeps its external level files. About the exact location of this directory you can read in the WhereAreTheFiles.pdf information file which comes with the game.
You need to have the registered version to play on these levels. Choose 'Play External File' from the main menu.
Warning: these levels are quite difficult.
