Nexus: The Jupiter incident is a science fiction themed real-time tactics computer game developed by the Hungarian based Mithis Entertainment that focuses on tactics and ship management instead of resource collection and base construction. Previously this game was called "Imperium Galactica 3"
In each of the game's missions, the player is given a small number of large space ships (always less than ten, and sometimes just one or two), along with accompanying fighters and bombers. The ships are large and cumbersome, and the battles between fleets protracted, giving the game a noted cinematic feel. Nexus uses the Blacksun Engine, made specifically for the game. Based on DirectX 9, it makes extensive use of vertex and pixel shaders, a parametric particle system, and other visual effects.
