Mega Man Star Force 4 was the canceled sequel to Mega Man Star Force 3. It entered production between 2009-2010, however it was cancelled midway through due to the underwhelming sales of Star Force 3 and Rockman.EXE Operate Shooting Star. It would have taken the series into a more mature tone and featured an older teenaged Geo Stelar with a new character, Kazuma, a descendant of Lan Hikari (and by extension his wife Mayl and their son Patch), becoming outlaw hackers who are sought after by the Satella Police for 8,000,000 Zenny a piece. Hacking was to become a large part of the plot or gameplay, akin to the Noise from Star Force 3. Other details are unknown. It was discovered on June 14, 2019.
