Langrisser (ラングリッサー, Rangurissā), originally spelled Lungrisser in the Mega Drive version and first released in North America as Warsong, is a tactical role-playing game developed by Nippon Computer Systems (NCS).

It was initially released for the Mega Drive/Genesis console and later the PC Engine (in Super CD-ROM² format), the former version being published by Treco in America.

The type of the available army depends on the hero class (e.g. Griffons can only be purchased by Dragon Knights) and have different prices.

Classes in bold shows the initial class for that character The storyline follows the armies of Prince Garett of Baltia as they battle the Dalsis Empire and the monsters they unwittingly awaken, framed as a battle between the forces of good and an ancient evil that threatens to overrun the world.

King Alfador sees the castle will not be able to stand and urges his son Prince Garett to flee to the town of Sulras, both for his own safety and to gather reinforcements from Duke Carleon.

He leads a campaign to retake the Castle, freeing the prisoners, but Dalsis has already taken the treasure Baltia was protecting, the magic sword "Warsong".

He rescues the fortress' commander Bayard, and begins his march through the Dalsis Empire towards Emperor Pythion's palace.

Garett retakes Warsong and begins his campaign against the evil, fighting ever more powerful monsters along the way and eventually tracking their source to the dark land of Seneferia.
