Trial by Radiation will take the player to the Mass Fusion Disposal Site to clear of hostiles. Upon returning to Mass Pike Interchange, the player will be granted rank of Recruit (if not already or is Infantry) and will be allowed to enter the Nuklearpolizei outpost as well as interact with the soldiers and merchant. Upon completion of the mission, Soldat Clemens will ask the player to look for a crashed Vertibird in to the south (Vertibird Wreckage) that the fleet had seen on their way to Mass Pike Interchange. The player may refuse or accept. If refuse, the player may inquire again later; if accept, the mission "Scavenger" starts.
Scavenger has the player travel into the Glowing Sea to find the Vertibird Wreckage. Once there, the player will find a steamer trunk with a holotape, Assault rifles and dog tags. (named "Vertibird C03-B223 Flight Log" opening up to error messages on the logs excepting the final log: "OCT 21, 2077: Core systems shut down. Rotary control system - unresponsive. Gyroscope - unresponsive. Distress signal - unresponsive. Radio communications - unresponsive. ERROR-ERROR-ERROR-ERROR-ERR...") Once the player has retrieved the holotape and returned to Soldat Clemens, the player will be rewarded with 200 caps and Soldat Clemens will become a companion.* The player may go to Geist Lukas for more missions. Such missions include clearing a site of hostiles, claiming settlements for the Nuklearpolizei or retrieving (randomized) junk for scrapping.
At level 30, a message over the Nuklearpolizei's radio frequency will alert all Nuklearpolizei to report to Geist Lukas for debrief on a classified mission. By interacting with Geist Lukas, he will mention that a final battle against the Children of Atom requires tremendous preparation and a large stockpile of medical supplies, food, water, weapons and ammo. The player will then be notified of having to go to different settlements (either allied to the Nuklearpolizei or not) and retrieve said supplies (similar to the side quests given by Proctor Teagan of the BoS, in which the player may purchase, persuade or threaten the settlement into giving supplies) which will put the player on track for becoming a Feldwebel.
If the player, instead, speaks to Geist Lukas about personally donating supplies, Lukas will inform the player that it would be better to get the supplies from the settlements and give them to Feldwebel Johanna. Speaking again to Lukas, a yellow speech check, orange and red speech check are presented: yellow-tell a Soldat to do it for you, orange-convince Lukas to allow you to donate your personal supplies, red-convince Lukas to initiate the final battle without the supplies. By passing a yellow speech check, the player will convince Lukas to get another Soldat to take your place (your reputation with the Minutemen and settlements are not harmed), by passing an orange speech check, you convince Lukas to allow you to donate your own supplies (donate 25 Stimpaks, 50 purified water, 25 food (any), 75 junk (any) and 100 rounds of 5.56 and Fusion Cells), passing a red speech check will persuade Lukas that the Nuklearpolizei are renowned for their capabilities and, thus, do not require so much to do this job.
If the player fails the yellow speech check, the player will be called a slacker and to get to work (end dialogue). If the player fails the orange speech check, the player will be firmly reminded that this is not a charity organization and to get the supplies from the settlements (end dialogue). If the player fails the red speech check, Lukas will become angry and belittle the player for trying to be so reckless as to potentially destroying an entire unit; threatening to not only strip the player of their rank, but exile the player altogether if they even think of saying that again (end dialogue). Regardless of outcome, the mission "Para bellum" will start.
