Rittai Ninja Katsugeki Tenchu: Shinobi Gaisen

Tenchu was re-released in Japan on February 24, 1999 with many updates, including different mission layouts, all the stages seen in the American and European versions (levels 4 and 5 were missing in the original) and four selectable languages: Japanese, English, Italian and French.

The main feature of this version was its mission editor. The possibilities in creating missions were endless and it generated a special edition disc with the 100 best missions created by Japanese players called Tenchu: Shinobi Hyakusen.
