Here is the Slayer Series. It has the most views of the Single Player section and was a great success (also, thanks to everyone involved, from those who rated it to those who played and gave feedback).
The premise is that one soldier found an artifact that allows him to warp time, similar to the technology used by Correction Nine, and that soldier goes on a killing spree when the rest of the Civil Security found out he worked for the Upsilons, a group of professional killers known as the bogeymen of armies.
The first mission is a tutorial and you control an overpowered soldier hired to rescue the protagonist after his cover was blown. The mission was made to be incredibly easy on purpose and the whole series is made to escalate in difficulty, ranging from very easy missions to medium ones. Harder missions will come soon with updates.
