The Ropalolyst fight can be summarized in two phases. Rhino and Chroma are ideal, but any tough Warframe will do. Pick a Warframe with a damage-boosting ability and high toughness. A decent Amp is also recommended anything better than a Mote Amp will do. Snipers like Rubico Prime are a good idea, but anything with high single-shot damage should do the trick. You'll want to bring a high-damage Radiation weapon to the fight with decent range. But before you go running off to fight this flying Sentient, it's best to be prepared. The end effect should be as planned, player receiving 2 CMs after destroying the very first Black Egg.To unlock the Ropaloyst node, you must first complete the Chimera Prologue quest- unlocked after completing The Sacrifice. If not, other group of items is the culprit, so after loading that previous savegame, another group should be used/recycled to finally determine which one is faulty and needs to get rid of. Which group exactly could be determined by trial and error - it's recommended to use/recycle one group, destroy one Black Egg and see if the player receives Cybernetic Modules from SHODAN. One has to load a savegame created before destroying any of the Black Eggs (ideally before entering Rickenbacker for the first time) and either recycle or use up a whole group of items (for example, all Medical Hypos) in inventory.

Fortunately, almost all of the time it is possible to avoid this.

The chance is rare, and the exact conditions have not been reproduced.

Use of cheat command summon_obj to summon items, even early on, may cause an issue where the first destroyed Egg will not be counted, preventing the game from progressing when the last Egg is destroyed.

All of the sixteen Black Eggs have to be destroyed, otherwise SHODAN will not permit the player to access the main part of the Bridge of the Rickenbacker.

The Eggs are similar to the standard Eggs of the Many, with the exception of being black and red rather than flesh-colored, and the fact that they don't open to release their contents when the player gets close. She explains that these Eggs will eventually hatch a new form of annelid 'which you will have no hope of destroying', and demands that they be destroyed. Upon entering the UNN Rickenbacker, SHODAN informs the player of a number of Black Eggs spread throughout the first deck of the ship. The new, unnamed form of Annelid they contain is laconically mentioned in the game, but never actively encountered.

All Annelid Eggs look alike until they open, except for the mysterious Black Eggs, a genetic experiment on the part of the Many.
