Driller Engine 2 Era

The Driller Engine 2 Era (ドリラーエンジン２の時代) was the second era of the Driller Engine series, and was considered to be the most iconic and popular era at the time. The addition of several new features such as multiple typefaces and adding gradients to sprites caused the era to become successful. Third party developers were able to take on more darker subjects, such as adding blood to their games and adding voice acting.

Music
Games could now use 12 channels per song, and added a new feature called instruments. All songs were produced in Impulse Tracker.

Touhou Project
Starting with Touhou 6: The Embodiment of Scarlet Devil, the series introduced a new mechanic: Spell Cards to both players and bosses.
