  • The achievement/trophy “Pen Pal” worth 20G/Bronze gets unlocked when you’ve “Used the TMD to find 15 Chrono-Notes in single player campaign.”
    There are more achievements/trophies for buying 10 different Hero Upgrades and 5 different TMD Equipment items. Luckily E99 tech is easy to spot in dark environments, because it has a yellow glow.
