There are three computers, two in the main room and one in theconference room. To access Lucy's computer, go to the computer on theanumus and pick up the pen beside it. To access Vidics, steal the penthat is in his pocket when you see him earlier in the game. Read allemails on both computer including the ones in the deleted section.After reading them, you can access the computer in the conference room.
To get easy kills, equip your hidden blade and press Circle to throw an enemy to the ground. While they are lying on the ground, press Square to stab them. This is very useful when surrounded by enemies or when assassinating targets.
Note: Only attempt this technique if you are skilled in the Rank 2 skill "Counter" and have enough Synchronization bars; one and a half rows of bars are enough. During battle, equip your hidden blade. With this is equipped, all of your counters will score an instant kill. You can even instantly kill tougher ranked guards (such as the Teutonic guards in Acre when hunting Sebrand). Also, most of the time, using the hidden blade in battle will scare the last one or two guards, causing them to run away. However, since you do not have a weapon that is sufficient enough to block a full sized enemy blade, all incoming attacks will hurt you.
During battle, if you see a guard you are fighting physically emote in any way, press Low Profile Assassinate while facing them to score an instant kill without the need to counter.
The best weapon when facing four guards or thugs is the Short Blade.
After getting the "target" to a safe area to "interrogate" them, punch them first, then "grab" them for faster completions. It will take about two grabs to quickly finish them. However, in the last three quarters of the game, you might have to grab them up to four times.
The Master will take away your ability to use radar and make it hard to see. This also allows him to hit you once and kill you. Lock on to him and use a throwing knife against him. This will take away his power to blind you and make him easier to kill.
The first part is simple. Take out your sword and fight all your previous assassination targets. They are fairly easy to kill. Only one counter is required to kill each of them. For the second part, as soon as Al Mualim releases you, use your Eagle Vision to spot the real Al Mualim--the one in yellow. Focus your attacks on him. In the third part, Al Mualim takes away your synchronization bar and radar, allowing him to kill you in one hit. Take out your throwing knives and look for the Piece of Eden in his hand. Once you see him, throw a knife at him. Then, just counterattack/grab break him. Repeat this until he says, "Damn you Altair!" Finish him off with your hidden blade or keep attacking him with your sword until he is dead.
To easily defeat a Templar, press L2 to lock on to him and quickly equip the hidden blade. Wait for him to attack you so that you can counter attack and kill him in one blow. This is better than the sword fight. If you counter with the sword, you will only knock him down and not kill the Templar.
When you first engage in combat mode against him (after fighting the duplicates of Al Mualim), lock on to him by pressing L2.
Immediately equip the hidden blade before attacking. Then, wait for a counter and you will defeat him with the first blow you hit him. Note: This is after you fight Al Mualim when he makes about six duplicates of himself.
Travel to the southwestern-most vigilantes in the poor district of Damascus. On one of the buildings around them is a outcropping in the wall. Climb on it and you will see that it looks exactly like G1 Optimus Prime in vehicle mode. Note that there may be more than one outcropping in the area, so look carefully. If you lose sight of the vigilantes, you have gone too far. Also, these types of structures can be found throughout the poor district.
Complete these in the following order to decrease the difficulty ofeach major assassination and lower the time needed to complete the game:
1. Visit Assassin's Guild. 2. Scan the city by first climbing all of the view points. 3. Rescue all citizens from the thugs. 4. Complete all of the informant's missions 5. Pickpocket the shysters in all of the pickpocket missions 6. Go back to the Assassin's Guild and get ready for the major assassination mission.
When you go to bed after Memory Block 2, you will notice your closet door is open. Press any button to get a piece of paper Desmond notes as a code. The code will unlock your bedroom door, which allows you to go out as often as you like after you go to bed, as well as to open the meeting room area. You can also pick up various items to unlock Lucy's password.
Complete the game and watch the entire credits. You will be given the access code for the computer attached to the Animus. Hack the computer to access an inbox, outbox, and deleted message. Look at the inbox and select the email about the conference room. You can go to the conference room and access it via the keypad.
To easily defeat William of Montferrat in Acre, after the guards leave William, drop down from the castle and kill William. Then, "de-target" or deselect and run up into the castle buildings and battlement to escape.
One item you can pick up after unlocking your bedroom door is Lucy's password. You can then investigate her e-mails, which entail a short secondary story line. After you complete the last Memory Block, go back outside your room and go to Lucy's computer. In "Deleted Items" is an e-mail which entails her talking to someone about a rescue, then the last reply comes back as:
WondEr Why It is everyone Laughs at you? i'll Let you guess. let's just say she's proBably gEtTing it bigger and better from someone else tHat isn't you. how can you hope to compEte? REst asSured there are sOme gOod ways. click the liNk to see!
Removing the capital letters out of the message decodes the message as:
When you go to Jerusalem and do the assassination where the guards are surrounding you, do not try to fight them off. Instead, turn around and run up the ladder to reach the second floor. A short intermission sequence will show your target running away and up another ladder. Hold R2 + X and run across the chandeliers, then run up the ladder to the right. Another short intermission sequence will show your target on top of another building. Chase him down and have your wrist blade enabled (press Up), then press L2 to lock onto your target while still chasing him down. When you get close enough, the word "Assassinate" will appear for SQUARE in the upper right of the screen. Press it to complete your task. After another intermission sequence, evade the guards by jumping onto building roofs, hiding, etc. Make your way over to the bureau to finish the memory.
Equip either the short blade or the sword and, when facing a large number of guards, just keep attacking them, bouncing one attack to one enemy then attacking the next. If one of the enemies tries to attack you while attacking another guard, immediately press SQUARE. This will allow you to attack while rapidly countering enemies. Another way is when the enemy dodges your attack then follows-up another attack. Do the same thing, but make sure your timing is good enough to allow you to survive even if there are six or more guards.
After killing Al Muaiam and returning to the real world, listen to the conversation about how they aregoing to kill you. Then, turn on your Eagle Vision and look at the floor to see some mixed up letters on both sides of the Amnius. You should see on the side closest to the main door:
M O R Y M N O E S E N C E O L C H T H O N B T L O T C T D E O S A T O A P E D S N L S T F L D D U O O E T E E A I E I R I N T H S H K T T K E R T U A A A N S S A
-To decode this, start reading at the bottom right hand corner to the top right hand corner, so you will start at "A" and stop at "S". It will spell a real word. Do this for all of the columns and it will read:
ARTEFACTS SENT TO THE SKIES TO CONTROL ALL NATIONS TO MAKE US OBEY A HIDDEN CRUSADE DO NOT HELP THEM
Next, do the same thing to the mixed letters on the other side of the Amnius:
A D R H O O D T M W H B I T D O E U S Y S I N S E A R O O M R E A Y N R I S E Y T N I D L M I D E T W I H W Y I E A U D A Y H T
It will spell out the following:
THEY DRAINED MY SOUL AND MADE IT THEIRS I DRAINED MY BODY TO SHOW YOU WHERE I SAW IT
When trying to "save a citizen", run in, assassinate one guard with your hidden blade, lock onto the closest guard, and hold R1. When the guard comes in to attack, press SQUARE to parry and kill the guard in one smooth, clean move. Repeat this for all guards to avoid taking damage.
