ドルアーガの塔
is an action role-playing arcade game released by Namco in 1986. It runs on Namco System 86 hardware and is the sequel to "The Tower of Druaga", which was released two years earlier. The game's story directly starts after the first game, where Ki and Gil must venture down in the Tower of Druaga and escape it. It is the second game in the company's Babylonian Castle Saga series, and was later ported to the MSX, NEC PC-8801, FM-7, and Sharp X68000 platforms. "The Return of Ishtar" was included in the compilation game "Namco Museum Volume 4" for the PlayStation, which is also the first time the game had been released overseas.
