Some simple ways to set some variables that impacts the endings:



Tanya gets caught by Julia early in the game when she is in Luke flat:

1) if playing as Tanya you picked the choice "Tina could prove dangerous"

2) if playing as Tina you picked the choice "Trust Agent Storm"

otherwise, Tanya won't get caught



Tom and Helen lovers

1) as Luke, treat Helen badly

2) as Tom, pick "I should take my chances..." when they're about to go jogging

3) win Helen boss fight with Tom



Jason likes Tanya: there are three degrees of likeness. You can meet him in two points.

meeting him with Tanya in the streets:

-1 = "Tell Jason you won't break his neck"

0 = choose: "Offer to kill someone for Jason"

1 = "Offer Jason some private time with you"

meeting him after Tanya is captured:

-1 = "Say you are Lucas Walker"

1 = "Say you're not Lucas Walker."



Tom suspects of Luke: early in the game when you choose the option if to trust Luke or not.



Luke gets depressed: this can happen in several ways.

1 = Tom and Helen are lovers, Luke still loves Helen (early decision at spaceport) and when he is coming back from Sarah's flat discovers them kissing. Either he wants to stop Sarah or he killed her in her flat

2 = If you win boss fight playing as Tom against Luke and you win



Tina solves the case, two conditions:

1) Tanya is not caught early, you meet Jason on the streets and have -1 relationship with him. He will say that you're a perfect distraction and run away.

2) As Tina, after Rob is killed, you search his stuff and find enough clues (3)



EARTH ONLY ENDINGS

------------------

For those endings, Mars plot must be over. A simple way to do it is with Tom failing boss fight with Sarah early in the game.



THE VACCINE:

Doesn't matter if Tanya gets caught or not. The important is that Jason is caught, so you must not have a bad relationship with him (0 or 1).

When you have to choose the brain to bring with you before the final scene, choose Lucas one



NOT GUILTY:

Like the vaccine, but don't be kind to Jason (-1), so he leaves Tanya and escapes. Tina fails to gather enough clues or is abducted/eliminated early.



THE PROMOTION:

Like previous one, but this time Tina gathers enough evidence and gets the visit of Jason that helps her.



BURIED:

Tina could be dangerous

You're caught, win first boss fight with Julia, need to have bad relationship with Jason (-1)

Bring Jason brain with you



GUILTY:

Like Buried ending, but Tina manages to gather enough clues, first winning boss fight against Rob and then examining his belonging (need to find 3 clues)



DEADLY BLONDE:

Choose Jason brain, and you were nice with him but not too much (score of zero). Nanotech gets destroyed, and Tina fails to gather enough clues.



MYSTERY WOMAN:

Like previous ending but Tina manages to gather enough clues.



Cybernetic World:

Like previous endings, but this time Jason likes you (1), so Tanya convinces him to release the virus in the final scene.



MARS ENDINGS

------------

Many Mars endings happen independently from Earth path until a certain point.



RUTHLESS:

You accept to work with Sarah, create the virus for Earth and kill Tom who suspected of Luke and came after him.



PROTECTOR:

You accept to work with Sarah, create the virus and manage to convince Tom and Helen to stay on Mars, becoming their protector. This needs that Tom doesn't suspect of Luke.



MARSICIDE:

Luke spreads the virus on Mars alone: for this, Luke needs to be depressed. It happens in scene where Luke goes back to the flat after killing Sarah. Either finds Tom and Helen kissing and he still loves Helen, OR even if doesn't love Helen, Tom doesn't suspect of him. In both cases Tom and Helen must be lovers.



NO TRUST:

Luke spreads the virus on Mars, had to kill Tom (he suspects of Luke), Helen listens to Luke because tomhelenlovers = False



KILL THEM ALL:

Luke copied the virus data, killed Sarah, spreads the virus on Mars, had to kill Tom (he suspects of Luke), Helen doesn't listen to Luke because tomhelenlovers=True and dies



FINALLY TOGETHER:

Luke is depressed and commit suicide, tomhelenlovers = True and Tom doesn't suspect of Luke, Tom and Helen escape Mars.



PUBLIC EXECUTION:

Like previous one, but Tom and Helen aren't lovers and they trust Luke (Tom doesn't suspect of Luke).



EARTH SWEET EARTH:

Tom, Luke, Helen destroyed the virus, Jason was caught so can't expose them. To reach this ending, you must not kill Sarah after spending the night with her, and you must advance Earth plot until Jason is caught and his brain extracted (you can then fail the last Tanya/Julia boss fight). Tom and Helen must not be lovers.



COMBINED ENDINGS

----------------



TOO LATE:

Luke is allied with Sarah and they prepare to spread the virus on Earth, but the virus has been spread already. You need to have Jason use the behemoth and be friend (+1) with Tanya on Earth path.



MY NAME'S LUKE:

Luke is allied with Sarah and they prepare to spread the virus on Earth, but Jason is not caught (needs to have -1 relationship with Tanya) and exposes Luke true identity to Sarah.



MOVING OUT:

Possible follow up on Mars ending 8: Tom, Luke, Helen destroyed the virus, Jason was caught so can't expose them and he didn't release the virus (jason relationship of 0 with Tanya). Tanya is alive. This ending changes slightly depending if Tom and Helen are lovers or not.



A NEW LIFE:

Possible follow up on Mars ending 8: Tom, Luke, Helen destroyed the virus, Jason was caught so can't expose them and he released the virus (jason relationship of 1 with Tanya). Tanya is alive. This ending changes slightly depending if Tom and Helen are lovers or not.



SHE HAS A SOUL:

Possible follow up on Mars ending 6: Tom and Helen are lovers, Tom don't trust luke and they both escape Mars, Jason was caught so can't expose them and he didn't release the virus (jason relationship of 0 with Tanya). Tanya is alive.



SWAN DIVE:

Possible follow up on Mars ending 4: Luke and Helen go back to Earth, Luke had to kill Tom and spread virus on Mars. Tanya gave control of behemoth to Jason who was neutral (relationship 0) to her.



TO THE MOON:

Possible follow up on Mars ending 4: Luke and Helen go back to infected Earth, Luke had to kill Tom and spread virus on Mars. Tanya gave control of behemoth to Jason who was friendly (relationship 1) to her.



ALONE:

Possible follow up on Mars ending 3 and 5: Luke returns to Earth alone, Tom/Helen are dead and meets Tanya. Tanya gave control of behemoth to Jason who was neutral (relationship 0) to her.



THE OFFER:

Possible follow up on Mars ending 3 and 5: Luke returns to Earth alone, Tom/Helen are dead and meets Tanya. Tanya gave control of behemoth to Jason who was friendly (relationship 1) to her.



LOST IN SPACE:

Jason is in control of the behemoth device and destroyed Nanotech. This in theory can be reached even only with Earth plot but wanted it to be a special bonus for completing both paths

Luke accepts Sarah's offer AND Tom and Helen are lovers.

That case wasn't included, so now I've added it to the Protector ending.

instead Luke asked for the help of both Tom and Helen to hack Sarah's account and destroy the virus.

not sure if Tom and Helen are lovers, although Luke did admit that he does not love Helen anymore !!

Tanya won the battle against Julia, chose Lucas' brain who betrayed her, then was captured .

Tina was brain-extracted and Rob was killed !

Jason was in good relationship with Tanya !

Jason = 1

Luke killed Tom and Sarah

Tina got abducted

Tanya killed Julia

Tanya helped Jason



I get No Trust ending, Lost in Space and Swan Drive each time
