Starglider 2 was an early 3D space simulator/flight simulator video game released in 1988 by Argonaut Games and was the sequel to Starglider.
The goal of Starglider 2 is to destroy an enemy space station with a neutron bomb, and the majority of the gameplay consists of collecting parts for the bomb, or fulfilling other prerequisites (e.g. finding the nuclear professor capable of constructing the bomb, or trade goods for the bombs necessary to destroy the shield generators protecting the space station), while fighting off enemy spacecraft, and delivering collected items to depots inside planetary tunnel systems. The various objects needed to complete the game are distributed across the many planets of the solar system, as well as in the intervening space (e.g. asteroids and space pirates), or even in the atmosphere of the gas giant planet.
