There's another story to tell
Publisher Arc System Works and developer APlus Games have announced that River City: Rival Showdown will include a special scenario called “Riki’s Story,” which will be available as part of the main story after you beat the unlockable “River City: Yamada’s Side” mode.
In Riki’s Story, you’ll follow Riki and witness his side of what went down during the four day period of the River City incident. What was he up to all that time?
You can also unlock Riki’s Story automatically if you have save data for River City Saga: Three Kingdoms on your Switch. River City: Rival Showdown is set to arrive on Switch October 12th, 2023 worldwide.
