Right, Down(2), Right. A sound will confirm correct code
tHint: Defeating the Black Baron
This fight starts with an air fight. First, shoot his ship down.
When you get to the fist fight, wait until he throws a big uppercut.
Hit him while he is stunned. When he gets to 2 thirds of his
health, he will send out guards to defeat you. If you got hurt, look
for health icons that they drop. When you continue the fight against
the Baron, he will have a 2nd attack. When he growls and gets
angry, he will jump on the wing of the plane. Jump to avoid this
attack. When he gets to one 3rd of his health, he will send out
more guards. When you defeat them and the fight continues, the
guards will still be coming. Use the guard that sprays oil and
ignites the oil against the Baron. Lure him to the oil and keep him
there until he is set on fire.

If you go back to Venice on Sly 3, you may notice the coffee house near the
police station is inacsessable. This is not true, if you know where to look.

Walk up to the front entrance of the police station(the vent on top has been
boarded up), and you will see an interaction symbol.

Hit the circle button to open the door. Instead of opening the door, the camera
will zoom across the plaza and open the coffeehouse door. When the room loads,
you will be in the coffeehouse! Not useless, and fun.

Complete 100% of the game.

Play as Bentley. Then go to where you can see her, then use the size destabilizer. hit her twice, then CONGRATS! YOU KILLED CARMALITA!

To defeat General Tsao on the treetops, wait until he super jumps
across the forest to try to hit you. When he does that, super jump
at him then double jump to change direction and hit him. Continue to
do this until you go to the forest. When the fight begins inside the
forest, it will be basic. Wait until he is done attacking, then hit
him. When he flies off, sprint to where he is and hit him again.
Once in awhile, he will duck down and rapidly spin. When he ducks,
jump away from him. When he is done with that attack, keep hitting
him. He will gain black magic powers at 2 thirds of his health,
but if you keep hitting him repeatedly, he will not have time to use
many of them.

Sly's a thief (duh), so be sure to pick-pocket all enemies before defeating
them. Items grabbed can be sold on Thief-net for more moves and abilities.

To defeat Don Octavio, wait for Sly's signal to lure Octavio to the
tar pit. Get close to the tar pit and wait until he gets stuck in
the tar, then punch him rapidly. Don has 3 attacks. He rams you,
punches you, and when half his health is depleted, he sends a sonic
boom toward you. When his health is half depleted, you will have to
run to another tar pit. Hold R1 to sprint and follow Sly to the next
pit. Run away or sidestep when he tries to charge at you, and back
away when he punches you. To dodge the sonic boom, jump over it or
back away from it.

To defeat Giant Carmelita, climb your way up to the mask hooks from
her feet. Be careful, as her henchmen will be trying to shoot you
down. When you get to the hooks on her forehead, hit them with your
cane.
