Silly hats
This is instantly unlocked when you unlock a new hat.
You can unlock new hats on the "Infiltration" challenges.
Power-up Orbs
In the Arcade levels, there are four power-ups. A description
and what they do follows:
Blue Orb with wings: Super-speed boost
Yellow Orb with helmet: Cloak of invisibility
Aqua Orb with divided sphere: Makes you smaller
Red Orb with spike: Power boost for strength
Faster reloads
Some guns have slower reload times than others. Instead
of pressing [Reload], press "Next Weapon" quickly followed
by "Previous Weapon" (or vice versa). When you switch to
a new weapon and go back to it, the weapon will automatically
be reloaded.
Mini-games
To play the mini games after they have been unlocked,
go to the temporal uplink and press [Triangle]. It will zoom
in and ask which mini-game you would like to play. If you are
playing in two player co-op mode, you can play two player mini-games.
Destroying the Bio-Hazard case
When you restore the power in the building, go down
to the "Digging Site". When you get there, you will
see a case with something in it. Make sure you have plenty of
Timed Mines. Walk towards it and throw four or five Timed Mines
at it then run away. When it blows up, the woman on the speaker
will start talking. People with very good guns (Flame Thrower,
Shotgun, Machine Guns, etc.) will appear. You will also have a
new objective to not let any mutants survive.
Destroying camera
Shoot the screen of the camera. This causes it to blow
out, conserving your ammunition. For turret cameras, shoot the
tip of the barrel since there is no screen.
Destroying gun turrets
To destroy a gun turret that is positioned on the ground,
shoot it in the screen that is located slightly above the barrel.
If the turret is positioned on a wall or above your head, then
the screen should be slightly beneath the barrel. The screen is
the blinking red and green light.
Fire immunity
The robot R-109 cannot catch on fire.
Saving time
If you are standing on a upper level area, and there
is another upper area next to you that you have to find a way
to get to, to save time, carefully go to the corner of the two
upper areas and walk across the very small area at the corner.
1853 Wild West: Defeating the Colonel
Save the black powder not needed to open the jail.
When it is time to defeat the Colonel, pour a trail of black powder
down the train tracks in the tunnel leading to his lair. Start
at the lamp near the mining cart and go down the tracks to where
the Colonel speaks to you. Once his health meter appears, retreat.
By shooting the lamp, it will fall and explode, setting fire to
the powder. The burning powder will race down the tunnel and set
fire to the Colonel, along with all the men with him who are chasing
you. If you keep running from the Colonel, the fire will eventually
finish him.
1895 Notre Dame Paris: Defeating
the Portal Daemon
When you encounter the Portal Daemon, stand behind
the center pillar of the landing, and arm your shotgun. Each time
he shoots the blue at you, duck behind the pillar. When he finishes
each shot, dart out and nail him in the head with your shotgun.
After doing this five or six times, he will fall over and die.
When you are fighting the Portal Daemon, pull out your (2x) Luger
pistols and fire them rapidly at his body. When he shoots at you,
take cover behind a pillar and shoot at him again.
1895 Notre Dame Paris: Saving the
maidens
When you get to the area of the level when you have
to save the maidens under the normal difficulty setting, save
the first two maidens. When you get to the third maiden, ignore
her. It is really a zombie in disguise. Instead, run over to the
fourth maiden and eliminate the zombies that are trying to kill
her. After you rescue her from the zombies, make sure she gets
to safety.
crossbow
Select the crossbow as your starting weapon. As soon
as the map has loaded, equip yourself with the crossbow. Search
the map for a tunnels with a flaming torch on either the left
or right side. Stand in front the torch. Use the Right Analog-stick
to look up at the torch. If done correctly, the tip of the arrow
should be burning. The flaming arrow can incinerate multiple enemies
at each time instead of just one.
1932 Chicago: Defeating Big Tony
Get Big Tony to come out, then hide back in the hallway
that you came out of. When Big Tony walks down the stairs, he
will stop. Snipe him in the head with any desired gun (sniper
rifle recommended).
1990 Oblask Dam Siberia: Anaconda
the dish
In the beginning of the level, make your way to the
upper section of the building with the dish. If you walk around
the catwalk, there will be a group of boards on top of the bunkers,
and one leading from the catwalk to one of the bunkers. Cross
the board and one in front of it (not the one on your left). There
will an opening on top of the bunker. Go in it and there will
be some timed mines. After that, leave and set a couple of mines
on the dish somehow. The dish will be destroyed, saving you the
trip back and forth. Note: If you check the bunker through the
door on the outside, it will say that the door is locked on the
inside.
1990 Oblask Dam Siberia: Ending the
1990 Oblask Dam Siberia: PA system
When you go underground into the research facility,
look up at the ceiling. Throw a timed mine on the speakers for
the PA system. After they explode, the PA system will produce
a cacophony of sound when the woman speaks.
1990 Oblask Dam Siberia: Extra Soviet
2019 Neo Tokyo: Easy completion
In story mode, instead of following the girl to the
gang's hideout, at the beginning of the level, wait for the train
to pass. Then, immediately jump on the back-most bottom support
rail. Have the Terminal Uplink out and jump down. If done correctly,
you should be in the streets with just a second or two before
the cameras catch you. Then, dive in and out of cover as fast
as you can, because you do not have to worry about the girl catching
you (because she is behind you). When you get to the stairway
to enter the sewers, do not go in. Instead, look for a crate in
the far left corner. Hide behind this until the girl arrives.
When she goes out of sight in the sewers, follow her as usual.
