Installation Instructions: (thanks Iammingy)
To install the mod correctly:
1. Back up your files - it will overwrite your herostat and other files. It will also reset your heroselect to include only the officials, you will have to readd other characters to heroselect.
2. Place OfficialCharsBV4.rar in ..\Activision\Marvel - Ultimate Alliance
3. Right click on OfficialCharsBV4.rar and click "Extract Here".
4. If it asks you to "confirm file replace", click "Yes to all", assuming that you have backed up your files already. If you haven't backed up your files, then click "No to all" and back up your files now.
5. Let it run for a bit.
6. After it's done extracting, the mod is ready for playing.
7. The default herostat contains Colossus, Hawkeye, Hulk and Moon Knight. You can swap in other characters with Heroselect. You can find the herostat entries of other "Official" characters in herostat.CFG from the "heroselect" folder.
