Can you help me to put Worms 3D New Maps to Worms 4 Mayhem?!

there are some people working on good methods of doing so. at the moment, you can only replace some w4 map with a w3d one, and there is nothing you can do about textures getting messed up. there is a .xan and .hmp files in w4 maps folder that you want to rename or move. then place w3d map there (.xom) and rename it to have the name of the file you just moved, including giving it a .xan extension. it should then take the place of the removed map in the game. the name and image associated with it will remain, though.

I' m actually working on it. ;)

you should be able to extract the maps without actually having w3d.

If you are realy desprate you can get two of them[they will be slightly diffrent]by doing death matches, they are: hold until reworked[hold until revived] and re-submission[submission]

i think he means the new fan-made maps for w3d.
