Deneb is the battlefront of the Itani/Serco war and is constantly under siege. You can participate in fighter, small, medium and large skirmishes that range in difficulty in the types of ships you would face and the number of kills that need to be made before the opponent disengages. Large skirmishes require 2000 kills, where as the fighter ones only require 20. In skirmishes where capital ships are present the number of kills is determined by the number of people on board. A Trident has 800 souls on board.
It is also possible to repair and re-arm for free in some of the capital ships when they are present.
Uncontested or won sectors contain defense turrets that once destroyed spawn a new skirmish to claim the sector.
