Worlds v1.4 is for version 1.3. It has 17 levels with 4 of them being secret levels. The file is 2.9MB in size and the file name is worlds-e.zip. It was released on February 23, 2000. Note: The included worlds.exe would not work for me. If you have the same problem a patch/bat file is included in the zip file.

Worlds v1.4 has good level design and gameplay for the most part. There is some new art but not a lot of detail. The weapon and alien strengths have been changed, some quite a lot. This is not a charge in and blast them all type mod. If you do you will most likely get killed very quickly. I rate it as good with 3 out of 5 stars.
