This transmission was replaced with a connectivity function and with Tetra's voice. The mode was originally shown in English; instead of two Japanese characters, players could choose a title of "Mr." or "Ms." followed by one English letter as an initial.

Tetra's Trackers was first shown at E3 2003 alongside as separate games. It was announced later that year that both games, plus a new one called Shadow Battle, would be included in the same disc.
