Soul Force

Soul Force The Soultron star system has been at peace for millenniums, the echoes of warfare long faded, its people living in hope for a never-ending peaceful existence.

Yet some had looked out into the skies, wondering what lay beyond, and what dangers could descend upon their peaceful worlds. In secret they developed project Soul Force, an advanced space fighter designed to defend the Soultron system from an outside threat.

And from the darkness of deep space comes a terrible bio-mechanical fleet swarming into the Soultron star system, monstrous creations descending upon the peaceful planets, tearing into the ground for reasons unknown. Communication attempts remain unanswered, the invaders obliterating any ship brave enough to approach...

We have chosen you to launch and pilot the new Soul Force space fighter against this terrifying threat and liberate our star system. Learn our enemy’s plans and put a stop to them for good. The fate of our star system lies in our hands. You are our last and only hope...

Soul Force – NTSC update & Outstanding Orders
Written by Protovision on 04.03.2021

We have identified a bug on the Icicka stage of Soul Force that appears only on NTSC machines. This bug has been resolved and you can access the Soul Force update via the original download link supplied to you previously.

For those who are still waiting to receive their physical copies of Soul Force – we have had to pause processing your orders as one of our UK based suppliers is currently not in a position to supply us with some of the package components. The supplier will be able to fulfil our order in the upcoming weeks but in the meantime we apologise for the additional delay in getting your physical copies. We will post an update to confirm when we are in a position to process the outstanding orders.
