Game developed by SNK in 1987.
Bermuda Triangle is a sliding shooter designed by the same team as Ikari Warriors.
The player must be able to survive and pass each of the 9 levels, which automatically scroll, and endure long enough to reach and destroy the boss.
The ZIG ship, being a much larger ship than most other ships, can sustain several shots before being destroyed and can hit both in front and shoot in 8 directions via a rotating turret.
SYD ships can be collected in various levels and will fly close to the ZIG in four different formations. They can block enemy hits but will be destroyed if hit by enemy ship hits.
Energy can also be recovered in order to restore lost health or, in the event that health is already at its maximum, activate the attack of the ships ZIG and SYD.
