Each winning ending is triggered by a different research. I’m not at home to give the names but you can find them on this forum.
Ending the research for one of them blocks you into one ending (even if you then do the research for an other faction).
Unfortunately nothing. If you don’t have saved game before Virophage Injector research you must do PP ending. If you have load it and skip Virophage Injector research.
Look there. When you finished one of those researches then you are locked in the ending of the game.
In my opinion the best way would be that you are allowed to research all and before the beginning of the Final Mission you could choose for which fraction you want to play the final Mission.
Currently you Play the final Mission for the fraction which research you completed First.
Strange, I am again at the point, where I can research the Virophage Injector, yet the
New Jericho last research point: Project Nemesis is not available. What have I done wrong?
Do I have to complete all available other research for NJ before I get the topic?
Are you allied with them? What is diplomatic percentage?
EDIT: I think you have to be 75+% with them to be able to do shared research. On 50+% level you only get their research once they finish it, you don’t contribute.
Just did this mission with 4 mortar Chirons. I forgot to put “+20 armor” from technician but my heavies lost only little health. My sniper on the other hand got some of it and nearly died. So I can confirm, remedy against Mortar or Goo Chiron, heavy armor.
I don’t know then. I have finished NJ ending but now don’t remember what exactly I had to research before Project Nemesis. I remember only that I have finished all their research before the final mission.
Whatever your play style is bring LOT of ammo. 2 priests with mind crush will help you very much. Save game before that mission because there is no evac area, if you lose you lose whole team.
I know this thread is old but I got the same problem. Project Nemesis isn’t showing up. I have only the option for the Virophage Injector. I researched nearly everything, I only miss some catched pandoran research for example the psychic influences research (Clarity Module) and the goo research (Goo Repeller). Are those two needed or do I miss something completely? The last research for NJ was the AI.
There should be a goal on the global view that NJ builds their big Command Center (or something similar) anywhere. If this is ready you have to defend it together with NJ troops against a big bunch of pandorans and after that you get access to Project Nemesis.
