District Control Gates are indestructible structures found throughout Solo Nobre. Their purpose is to control ground access to the Districts, opening or closing by NEP control.
The SNC have found a way of temporarily controlling the District Control Gates, allowing a sole Brigador to enter a district and eliminate any marked targets. Once the SNC is satisfied with the Brigador's completion of primary objectives, the SNC then open the gates, allowing the Brigador to escape.
In the Audiobook, the SNC open all district gates in Solo Nobre.
