The latest DLC for The Callisto Protocol serves as the concluding chapter of protagonist Jacob Lee’s story. Here, the biophage virus threatens to escape from the Black Iron Prison, posing an even greater threat to humanity. You must stop it!
To do so, you navigate the derelict ruins of the Black Iron Prison and once again have to cope with limited resources. In a race against time, you must find important data from Mahler – the only hope of containing the epidemic – and finally leave the moon with it.
You can play the Final Transmission DLC for Callisto Protocol since 29 June 2023
