Shining Force II, also known as Shining Force II: The Ancient Seal (シャイニング・フォースII 古えの封印, Shainingu Fōsu Tsū: Inishie no Fūin), is a tactical role-playing game for the Mega Drive/Genesis console developed by Sonic! Software Planning in 1994. The storyline is not directly connected to the original Shining Force, although a Game Gear title Shining Force Gaiden: Final Conflict links the two games' plots.
The game is much longer than the first, and more free-roaming. There is no chapter system, so the player can return to previously visited parts of the world. There are also two different ways of promoting many characters.
