There are two points in the game which affect the final battle. First of which is finding and saving Jade at the orphanage from the Oracle. Second is your choice to give Jade to the A.I. or not. Note that failing to save Jade from the Oracle will eliminate your choice to give her to the A.I. Despite any of your decisions at these two points, you can still attain each and any of the three final endings. What does change are very slight factors such as whether you arrive at the base with Jade or not, who you fight first and second, and whether or not there will also be soldiers there. Read each section for more information.
1. Oracle / Orange Clan wins
How-To:
Lose to the Oracle in the final battle.
-If you refused to give Jade to the A.I. (Agatha's form):
You will fight the Oracle first. When battle begins, simply let yourself get
hit by the Oracle's attacks, and Lucas will fall to the ground. At this point
you can now take control of Carla. Let the timer run out for Carla, and the
Oracle will automatically win. The A.I. will not show up at all.
-If you gave Jade to the A.I. (Agatha's form):
You will fight the A.I. first. Defeat the A.I. and the Oracle will reveal
himself with Carla at gunpoint. Take the Oracles offer to save Carla and he
will knock you both out and take Jade. There will be no soldiers to deal
with.
-If you failed to rescue Jade and the Oracle took her:
You will fight a soldier first (and timer). You can choose to pick up the
metal and hit the soldier with it, or use your powers. You can also let the
timer run out, which changes the next dialogue slightly. Next, you will fight
the Oracle. Let the Oracle beat you. Carla will not be available this time,
so you lose automatically. The A.I. won't be there.
2. A.I. / Purple Clan wins
How-To:
Lose to the A.I. in the final battle.
-If you refused to give Jade to the A.I. (Agatha's form):
You will fight the Oracle first. Defeat the Oracle with Lucas or Carla.
a. If you defeated the Oracle with Lucas, you will fight the soldiers next.
Finally, the A.I. will arrive to fight you. Lose to him here.
b. However, if you defeated the Oracle with Carla, the A.I. will appear and
kill the soldiers, then knockout Carla. At this point Lucas will regain
consciousness. As Lucas, lose to the A.I.
-If you gave Jade to the A.I. (Agatha's form):
You will fight the A.I. first. Lose to the A.I. The Oracle will arrive
(without Carla) to battle with the A.I. You can now switch to Carla if you
so
choose to. Lucas is now out of your control, and will attempt to take Jade
to
the altar (for the A.I.). Let the timer run out, and the A.I. will defeat
the
Oracle. There will be no soldiers to deal with.
-If you failed to rescue Jade and the Oracle took her:
You will fight a soldier first (and timer). You can choose to pick up the
metal and hit the soldier with it, or use your powers. You can also let the
timer run out, which changes the next dialogue slightly. Next, you will fight
the Oracle. Defeat him with Lucas (Carla will not be available to save you
if you fail at this point). Finally, the A.I. will appear, so lose to him.
The game will allow you to switch to Carla. Let the timer run out instead.
3. Lucas / Humanity wins
How-To:
Defeat all opposition (one way or another) and allow Lucas to willingly take
Jade to the altar.
-If you refused to give Jade to the A.I. (Agatha's form):
You will fight the Oracle first. Defeat the Oracle with Lucas or Carla.
a. If you beat the Oracle with Lucas, deal with the soldiers, then the A.I.
b. However, if you defeated the Oracle with Carla, the A.I. will appear and
kill the soldiers, then knockout Carla. At this point Lucas will regain
consciousness. As Lucas, defeat the A.I.
-If you gave Jade to the A.I. (Agatha's form):
You will fight the A.I. first, BUT, you can choose to defeat the A.I. now
or
later.
a. If you defeat the A.I. first, the Oracle will reveal himself with Carla
at
gunpoint. Refuse to give Jade to the Oracle. Carla will counterattack the
Oracle, steal his gun, and defeat him with it. There will be no soldiers to
deal with.
b. However, if you lose to the A.I., the Oracle will arrive (without Carla)
to battle with the A.I. You can now switch to Carla if you so choose to.
Lucas is now out of your control, and will attempt to take Jade to the altar.
Switch to Carla as soon as possible and take her inside. Wake up Lucas before
the timer runs out. The A.I. will defeat the Oracle and interrupt Carla. It
will knock Carla out, but you will regain control of Lucas. Defeat the A.I.
-If you failed to rescue Jade and the Oracle took her:
You will fight a soldier first (and timer). You can choose to pick up the
metal and hit the soldier with it, or use your powers. You can also let the
timer run out, which changes the next dialogue slightly. Next, you will fight
the Oracle. Defeat him with Lucas (Carla will not be available to save you
if you fail at this point). Finally, the A.I. will appear. From here, you
can
choose to defeat the A.I. now or later.
a. If you defeat the A.I. immediately, the battle is over then and there.
b. However, if you lose to the A.I., you are then given a choice to switch
to
Carla. As Carla, reach Lucas before the timer runs out. Carla will be knocked
out, but you will regain control of Lucas. Defeat the A.I. with Lucas.
