BBC Micro / Electron F14 Tomcat (c) Players software/D'N'A conversions by Adam Polanski

F14 Tomcat by Kees van Oss, 2015

Introduction

Tomcat is a vertically scrolling shoot 'em up in which the player takes control of an F14 Tomcat fighter aircraft, shooting at both air and ground targets whilst flying over four levels. The game is set in the future, some time after the first half of the 21st century. In the in-game universe, materials science has progressed such that human civilisation has found a way to cheaply build many artificial islands. The game is set on one such island, called ARTROCK 6 which is a completely automated defence installation. Due to a freak storm damaging the controlling software, the island has turned against its own side and has started attacking local shipping. The player's task is to fly in and completely destroy the rogue island.

Retro Software is therefore proud to reveal a brand new Atom port by the Dutch coder Kees van Oss. This new release is an astonishingly accurate version of the original title. The conversion was 'relative' easy because the resolution of the screen matches perfectly the Atom CLEAR4 resolution. Because it's a monochrome game, the graphics are exactly the same as the original Electron game. In the original game there were not many sound effects but they are also included in the Atom version.
