The title says it all, I am making a level pack and I don't know how to put all the levels into 1 wad, Any help?

Make a new map separately and then use Save Into on the same wad file.

Alternatively, copy the marker lump and all relevant lumps thereafter (THINGS, LINEDEFS, SIDEDEFS, VERTEXES, SEGS, SSECTORS, NODES, SECTORS, REJECT, BLOCKMAP) from one WAD to another using SLADE or similar. Make sure you don't accidentally put one of those lumps from Map A under the header for Map B, or Bad Things will happen.
