The Invasion

The Invasion is Bundled With SMBX Version 1.1, But Replaced With "The Invasion 2" in Version 1.2 and 1.3. It has more bonus area than its sequel.

The Invasion is like its sequel, but with 12 bonus areas and without the slopes, custom graphics, other styled dungeons, and the bosses other than Boom Boom and SMB3 Bowser Koopa.
