Zone Lambda is a "Great Cliff" and is Stage 5A of G-Darius. This zone is the upper stage of the game, it splits in Areas U and V. You start on the cliffs and then you will go up into space and see Lightning Coronatus, boss 5A of the game.
See Lightning Coronatus for further information.
Lightning Coronatus dies in a fiery explosion as the Silver Hawks attempt escape however Lutia's ship is badly damaged in the explosion, forcing her to bail out before it self-destructs. Floating in the darkness of space, Lutia is soon joined by Sameluck who abandons his ship and leaps towards her. The two are assumed to embrace as Sameluck's ship continues to drift in space without it's pilot.
