The final four movies are unlocked when the game is successfully completed on the hard
The first bonus movie is unlocked after Mission 5 (McKenzie Airbase
Exterior) on the hard difficulty setting. Lian will say "Got it" as she is
flying away in the helicopter to confirm the secret. The movie is called "Before and
After I" and is on Disc 1. It has some behind-the-scenes footage of an early
rendition of Gabe. It contains CG footage of Gabe running through the missile silo from
the first Syphon Filter. Gabe does not look very detailed and the silo looks
completely different. Then the movie transitions to the finished version seen in the game,
with Gabe confronting Markinson.
The second bonus movie is unlocked after Mission 10 (Morgan) on the
hard difficulty setting. Gabe will say "Got it" after he finishes receiving the
incoming radio call to confirm the secret. The movie is called "Before and After
II" and is on Disc 1. It has some behind-the-scenes footage of a later version of
Gabe and an early version of Lian. It shows Gabe and Lian sneaking through the Costa Rican
rain forest from the opening movie of the first Syphon Filter. Gabe has a gray
short-sleeved shirt on and camouflage pants and Lian is dressed in a black tank top and
camouflage pants. Then the movie transitions to the finished version seen in the game,
with Gabe and Lian sneaking through the forest and coming across the burnt out lab.
The third bonus movie is unlocked after Mission 16 (Aljir Prison
Escape) on the hard difficulty setting. Lian will say "Got it" after she and
Gregorov reach the escape point to confirm the secret. The movie is called "Deleted
Scenes" and is on Disc 2. It has four FMV clips that were not used in the game. The
first one shows the Chinese general demanding shipment of the Syphon Filter virus. The
second shows Archer in the Blackhawk swooping low over Gabe, who is on the back of the
burning United Pacific train. The third shows Gabe and Teresa in the beat-up rental van
they use during the Moscow missions (where Lian is chasing Gregorov), the van will not
start and Gabe gets out to push. The fourth shows a bag lady pushing a shopping cart
across the street in the New York Slums district, Mara Aramov's limousine smashes the
shopping cart and then screeches around a corner.
The fourth bonus movie is unlocked after completing the game on the
hard difficulty setting. The movie is called "Congratulations! Party time!" and

Agency Computer Lab multi-player stage
In the second room at the start of the Agency Bio-Lab Escape level,
(after receiving the incoming radio traffic) are two vents that you can crawl through. The
one on the left is the correct exit out of the Bio-Lab. The other vent leads back the way
you came toward the Operating Room where you overheard Dr. Weissinger in the previous
level. Head down this second vent back the way you came from. When you exit the vent,
there will be one Unit 1 trooper on the left in an alcove. Run past him down the U-shaped
hallway which leads to the Operating Room. You should be able to see the autopsy table
through the door. There are three more armored troopers in the operating theater, one low
by the door and two on either side up in the theater seats. Roll into the room past the
low trooper. If this is not done, when you get near the door he will run in front of it to
block your path. Run immediately toward the table with the computer. Climb up on to the
table, and then up onto the balcony (you will probably get shot up pretty bad while
climbing up). Then, roll toward the center of the back wall and into a small room. There
is an M-79 grenade launcher in this little room which unlocks the Agency Computer Lab map.
Gabe will say "Got it" to confirm that it has been collected. You do not have to
finish the level for the map to be unlocked.
Bunker multi-player stage
Find the PK-102 in the Moscow Streets level. There is a point where
two cars will try to run you over at the same time, and you have to leap and grab a pole
above you to avoid them. After this happens, drop down, and go back and search the two
newly crashed cars. Face the tail ends of the cars. The car on the right has the PK-102
inside. The cars are on fire, so search carefully. Additionally, after the cars crash an
enemy will get out of each car. At least one of them has a M-79 grenade launcher.
Caves multi-player stage
Find the binoculars in the Colorado Interstate 70 level. They are
located behind the first closed door on your left that you reach. Press Triangle to open
the door. This reveals a passage. Go left, open another door, and enter the room. The box
containing the binoculars is in this room.
D.C. City Park multi-player stage
Find the dirty laundry in the New York City Slums District level in
one of the washing machines in the first Sniper Building of the level. This is the
building that is similar to the slums district level in multi-player mode.
Disco Underground multi-player stage
In the Disco 32 level, after killing the bodyguard on the catwalk,
three more guards will run in the door. Kill all three before they can throw a grenade at
you. None of them have flak jackets. When you kick open the doors to the next dance floor
with big speakers in the corners, you will need to kill these three guards before the
guard above you can throw a grenade. Save your BIZ-2 ammo for him, run to the right, and
hide behind the speaker. Kill the two guards on the floor. As the guard above you runs
around so he can throw a grenade, use the BIZ-2 for a head shot. He does have a flak
Jungle multi-player stage
Kill Archer at the very end of the C-130 Wreck Site level with one
shot (head shot). It is recommended that you use the silenced sniper rifle to kill him
because of its zooming capabilities.
Pharcon Site multi-player stage
Find the girlie mag in the Pharcon Lab, after you taze the guards.
It is located after you go through the Mars exhibit.
Prison multi-player stage
Complete the Aljir Prison Break-In level without using the crossbow.
You will have to sneak and roll up to the first man before he makes it out in the open.
Roll a lot, but do not roll into him. You also cannot run or he will turn around. You
should be able to run up very close to the male guard and the female guard who chased down
the second prisoner. The last guard turns and looks around quite a bit. Walk against the
left wall, and hide behind the support. He will walk out past you, and then you can get
Rockies multi-player stage
Find the H11 sniper rifle on the first level (Colorado Rockies) to
unlock the Rockies multi-player map. The H11 is near the waterfall and ice arch where you
first meet Chance. Instead of jumping over the waterfall chasm, hang from the edge of the
chasm and drop down into the tunnel. The H11 is in there.
Surreal multi-player stage
In Volkov Park, kill the first guard to the left very quickly before
he destroys the car. After you kill him, collect the BIZ-2 in the car he did not destroy.
Additional multi-player characters
Find the M-79 grenade launcher on the second to last level (New York
Sewers) to unlock the following seven multi-player characters: Ninja Gabe, Scuba Lian,
Unit 1 (armored trooper from the Bio-Lab Escape level), Dr. Elsa Weissinger, Uri Gregorov,
Lawrence Mujari, and SWAT officer (helped in the New York Slums level). The M-79 is near
the end of the level (in the parking garage). Near the top of the stairs is an open
doorway into the parking garage, where a black van is driving past. Instead of exiting the
stairwell at that location, keep climbing up the stairs. There will be five Agency
operatives scattered on the landings above armed with silenced HK-5s, grenades, and M-79s.
Use the M-79 to clear them out. The M-79 is on the top landing.
Complete the C-130 Wreck Site level in under three minutes to unlock
