Unfortunately, due to changes in my time and lifestyle after starting my new job, I haven't got enough time to run Spearhead alongside Shattered Steel to the standard and involvement I'd like, as well as having time to also have a life otherwise. I've also lost interest in the premise a bit for the meantime, alas. 
As such, I'm putting it on indefinite hiatus for the meantime. 
I apologise for the disappointment, but I'd rather do it officially than just letting it die by negligence and disinterest.
