Prehistoric Isle 2

Prehistoric Isle 2 is a horizontally scrolling shoot 'em up released by Yumekobo in 1999 and published by SNK. It is a sequel to Prehistoric Isle in 1930.

Story
The plot takes us this time in the future where there have been a series of attacks in some parts of the world, leaving destruction in its wake, all this is caused once again by a invasion of legions of dinosaurs. To control this disastrous tragedy, the army sends two of his best helicopter pilots armed with high-tech weapons, with which it hopes to eradicate the prehistoric menace.

Gameplay
The players controls one of two types of helicopters. The main difference between them is in the type of weaponry, both are re-powered by a series of power-ups which are obtained by eliminating the enemies. The blue helicopter has a wide and straight ahead shot and the bomb is a huge powerful wave cannon, while the green helicopter fires a spread shot and the bomb fires a multitude of grenades that eliminates effectively the enemies in front. During the stages several civilian survivors must be rescued, which will give bonus points and power ups before the boss encounters.

Development & Release
A sequel to the original Prehistoric Isle was teased at the end of its credits sequence, but was not officially announced by SNK until a decade later. Masanori Kuwasashi, director of The King of Fighters '94 and The King of Fighters '95, submitted a proposal he worked with Samurai Shodown designer Yasushi Adachi for the sequel after the release of Quiz Meitantei Neo & Geo: Quiz Daisōsasen Part 2 (1992), but was initially rejected by SNK's management.

Prehistoric Isle 2 was co-developed by Saurus and Yumekobo, with James H. Woan, Nobuyuki Tanaka and Shuji Takaoka at the helm as producers. Masaaki Yuki acted as main programmer, while a planner under the pseudonym of "Barso" served as designer alongside Tomonori Nagakubo and Y. Yonezawa, in addition of Masahiko Hataya acting as composer. Several staff members also collaborated with the project. The game was first released by SNK for the Neo Geo MVS board on September 27, 1999. The title has since received a re-release by Hamster Corporation in recent years on digital distribution platforms such as the Nintendo eShop, PlayStation Network and Xbox Live
