At first glance a sequel to Katakis or yet another R-Type clone if you prefer, still the story of this one is a little different. As far as I remember, did Rainbow Arts try to create an Arcade machine at the time. When at some point this got shelved, the graphics and probably other things got salvaged into X-Out (=> "Crossout", I'm sure you guessed it

).
Since the main Rainbow Arts staff was busy with Turrican I/II at the time, it can be considered a production of their B-Team I guess. At least the Miggy version had music from Chris Hülsbeck and the C64 version graphics from Andreas Escher once again.
I decided to feature the C64 version here. No special preference here, but besides...
