Secrets

All six endings, the alternate S Scenario, and the unlockable Special Scenario.

Endings

Scenario A

Best Ending

The most complete ending in the game, with the best outcome for every character.

Unlock Condition
Save Billy (correct blood transfusion, and return his vest), recover Disc A from the Ambassador's hidden room, give Mason Disc A instead of the real disc, and separate the engine before the final fight

Scenario B

Alternate Ending

An alternate ending with a few key differences from the best one.

Unlock Condition
Same as Scenario A, but hand Mason the real Secret Information Disc instead of Disc A, and defuse the final warhead with more than 8 minutes left on the timer. Also triggers automatically if you follow every Scenario A step but forget to separate the engine

Scenario C

Alternate Ending

Another variant determined entirely by how quickly you defuse the final warhead.

Unlock Condition
Same start as Scenario B — Billy saved, Disc A recovered, real disc handed to Mason — but defuse the final warhead with less than 8 minutes left on the timer

Scenario D

Alternate Ending

An ending where Jack is forced to negotiate without Disc A as a bargaining chip.

Unlock Condition
Billy saved, but you never check the Ambassador's hidden room for Disc A, so you have no alternative disc to offer Mason at all

Scenario E

Alternate Ending

Several later scenes play out differently once Billy hasn't been saved.

Unlock Condition
Billy is allowed to die (wrong blood mix, or his vest never returned), but Disc A is still recovered from the hidden room

Scenario F

Worst Ending

The least favorable of the six possible outcomes.

Unlock Condition
Billy dies, and Disc A is never recovered either

Unlockables

Special Scenario

Unlockable Mode

A bonus mode built for replaying the game without worrying about ammo.

Unlock Condition
Finish the game on any difficulty
Rewards
  • Start with infinite dual handguns
  • An Assault Rifle with infinite ammo and grenades waits in Car 11's kitchen

Scenario S

Unlockable Mode

An alternate version of the story with several changes: the first boss fight happens on the Blue Harvest's roof instead of the adjacent train (and can even be punched to death at close range), a mid-game detour lets you briefly play as Christina rescuing Jack from a church hideout in Germany, Boris drops the IC Chip in addition to his usual items, the Pliers and Endoscope are swapped for a small key that unlocks a locker holding them in Car 6's lab, and the final fight with an injured Mason becomes hand-to-hand instead of another helicopter chase.

Unlock Condition
Finish the game on Normal or Expert
Rewards
  • Clearing it unlocks a mode that starts you off with infinite dual handguns and infinite assault rifle ammo from the very beginning
