Preparing Your Work for Upload

In this article, we’ll go over some recommendations on how to prepare your creations for release on our website.

Packing a GRO Archive

The easiest way to pack a map is by using AutoGro — an old but very useful tool. Here, however, we’ll explain how to pack a GRO archive manually.

A file with the .gro extension is simply a ZIP archive.
Files inside must be placed in the same folders as they would be in the main game.
For example, if a texture is located in TexturesMP/New/MyTexture.tex, it should have the same path inside the archive.
You don’t need to include original game files.

You may use compression when creating the archive, except in cases where the level is long or uses external music.

If your map uses a .dll, you should pack it together with the finished .gro file into one more archive.
Place the DLL in the Bin folder inside that archive. This way, it can be simply extracted into the game’s root folder to play.

We also recommend including the DLL inside the .gro itself — this ensures it won’t be lost if the GRO file is distributed separately in the future.

Always test your finished archive on a clean copy of the game.

Additional Recommendations

You’ll greatly help us if you provide screenshots of your work yourself.
Additionally, you can prepare a preview image for the map catalog — a square picture, at least 350×350 in size.
