The campaign for the Planet of Nemesis Tersera began with the Imperial forces conducting a bold assault on Orbital Laser Canaba. Defending the facility were a small group of Chaos Space Marines. Due to harsh snow storms, the Chaos forces were unable to effectively target the oncoming Dark Angels and Blood Angels. The majority of the combat was conducted in brutal close quarters combat - where the Blood Angels excelled. Orbital Laser Canaba was captured by the Space Marines.
