Here's the B-movie plot that holds it all together.
In a distant future, spread across thousands of colonies, the empire is under attack from a mysterious, unknown sickness that is affecting people’s minds. So far, you’ve been able to remain healthy but you don’t know for how much longer.
As one of the few survivors of this bewildering plague, it’s up to you to seek out and destroy the enemy that unleashed this madness. If you don’t, there remains no hope for your planet or your people. Are you prepared to tackle 31 missions and destroy the heinous foe?
Having worked through the game before, I'm glad to say the difficulty curve and the controls feel just as sharp and well balanced on Windows Phone as they were on the PSP.
You can grab the free trial and find out for yourself if this is for you - it's certainly one I would recommend.
