Mission 5: Voidsong in our Warhammer 40,000: Space Marine 2 co-op playthrough! We head to the planet Avarax to reach the astropathic relay and send a message to Lord Calgar.Along the way, we battle through Tyranid swarms, face a Carnifex boss fight, and deal with the mysterious arrival of the Thousand Sons.
