This mod has several goals. To provide a more emotionally engaging antagonist than Kai Leng. To engage with Miranda's reluctance to believe in Cerberus' malevolence during Mass Effect 2. To give Jacob a stronger narrative role during Mass Effect 3, allowing him to either follow through on his promise to take down Cerberus if they step out of line, or pay the price for his decision to work with them.
The Videos tab showcases most of the major changes.
You must install this mod before confronting the Illusive Man on Mars or it will not work.
FAQ
What determines who takes the Assassin role?
Miranda is far more loyal to Cerberus than Jacob during Mass Effect 2. The premise is that if they are both convinced to run for it, Miranda is more capable of evading Cerberus, but Jacob is likely to leave earlier and get a head start. Unless Miranda's loyalty to Cerberus has been sufficiently eroded and Shepard has demonstrated exceptional faith in her.
Mechanically this means that Miranda will be the Assassin unless:
(1) Miranda is loyal
(2) The confrontation with Jack is resolved via a charm or intimidate option
(3a) you choose her for both leadership positions during the suicide mission or
(3b) you choose her for one leadership position during the suicide mission and she verbally resigns from Cerberus if she's in the active party when Shepard chooses to destroy the base.
Warning: the vanilla game does not record Miranda's resignation, so this option is only available to people who played Mass Effect 2 while using the Unofficial LE2 Patch. If you did not then she would need to be assigned to both leadership positions.If either Jacob or Miranda died during the suicide mission at the end of Mass Effect 2, th
