Never ending Fight

We are team Dark Mist
I was the Sniper
The Ginger was the Medic
The blonde was the Demolish
And there was the twins with black hair
One was the knife expert
The other one was the Runner (spy technical)
The other team were called The Forerunners... They were a mystery but we knew after some spying ...
The leader was also a sniper and the others were guards/Defenders (had shields) and with black hair. The sniper hair color was a mystery. No one ever seen the sniper face... Not even his team. But that was all going to change when the two Best Snipers in the war between the "Forerunners and Dark Mist" meet face to face during the fight... But first to the beginning of the story...
