Seiren is the third stage from Thunder Force III.
Details[]
Seiren is one of the planets from the ORN System, being entirely covered by water. This level takes place underwater, with many air pockets which cause the ship to slowly drift upwards, coupled with the rough terrain which the player must maneuver around.
Trivia[]
- Seiren is named after the Sirens, a group of mermaid or harpy-like humanoids that lure unlucky sailors to rocky coves, where they eventually drown by shipwreck.
