About Undeadline
Undead Line is a top-down arcade shooter with scrolling screens, like Commando and other games. The player controls a character (from a selection of three on the MSX 2 version) that shoots projectiles at enemy monsters. The six levels available are presented in a menu and can be selected and played in any order. There is a boss battle at the end of each one. Chests with power-ups are scattered throughout the levels. They open when shot, and in the Genesis version it is possible to cycle through the available power-ups by keeping firing at them. The power-ups include armor and speed boosts, and several types of projectiles.

A challenging T&E Soft shooter that is one of the pricier Japanese carts.
Undeadline is a vertically scrolling shooter that began on the MSX2. The Mega Drive version came out in Japan only, from Palsoft on 20 December 1991, with T&E Soft as developer. In it you cycle through weapons and power-ups by shooting them.
Games-X commended the detailed backgrounds, enemy animation and atmosphere, but counted the difficulty, even on the easiest setting, against it.
How the Sega Genesis version differs
In the Mega Drive version, power-ups in treasure chests can be cycled through other weapons and power-ups by firing at them.
The Mega Drive port, like the X68000 one, came after the MSX2 original and was published by Palsoft.
Also on other platforms
MSX2 · X68000
- MSX2. The MSX2 original came out in 1989, and the MSX2 and X68000 versions both later got physical re-releases from Japanese retailer BEEP.
Before you buy
The Japanese cartridge is a different shape from a Western one and fits a Western console only with an adapter or after removing two plastic tabs in its slot. Among Japan-only carts it is one of the pricier ones, and the risk tier is medium, so ask for a photo of the board.
