Flow of Poison

Flow of Poison was a virtual representation of one of Altaïr Ibn-La'Ahad's genetic memories, relived by Desmond Miles in 2012 through the Animus.

Description
Having learned from Basilisk about a plot to poison Acre's water supply, Altaïr set out for the city.

Dialogue
A nearby building collapsed, blocking Altaïr's path and alerting the local patrol. Altaïr used smoke bombs to evade the guards, and proceeded to scale the rooftops. Altaïr cleared the gap and maneuvered around the obstacle in the street, returning to ground level. Altaïr eliminated the guards and continued through the street, careful to avoid falling balls of fire. He proceeded to the rooftops and killed two archers, noticing more guards on the ground. After shooting the guards below and killing two more archers, Altaïr returned to the ground. A nearby building collapsed on some guards. Altaïr killed the remaining guards and made his way through the street. Altaïr eliminated the would-be killers. After dealing with the guards, Altaïr continued down the street, coming upon a lifted box. After taking care of the guards, Altaïr released the lever, causing the box to drop. Altaïr climbed the box and returned to the rooftops, encountering a series of gaps in a nearby wall. Altaïr successfully crossed the gap and returned to ground level, where he was met by a few Templars. Altaïr defeated the Templar leader and broke through the shield barricade. He approached the city gate, where he noticed Saracens approaching. The Crusaders managed to destroy the gate and kill the Saracens. Altaïr defeated the initial intruders. Altaïr fired the catapult at the structure around the destroyed gate door, causing it to collapse and bar any more Crusaders from entering. He then scaled the city wall. Altaïr defended the city wall and made his way back to the street. Altaïr eliminated the executioner and continued along the rooftops, where he encountered an archer. Altaïr acquired the knives and crossed the rooftop safely. Altaïr approached the prisoner. Altaïr killed the guards and saved the woman. Altaïr eliminated the archers and approached the city gates. Altaïr scaled the city wall. Altaïr used the ballistas to secure a safe path to the camp. Upon nearing the camp, Altaïr was met by some guards. Altaïr relinquished his weapons, save his Hidden Blade. Against the guard's order, Altaïr entered the camp. Altaïr killed the soldier and donned his guise. While walking through the camp, as to not draw attention to himself, Altaïr was often addressed by his fellow soldiers. Attempting to get further into the camp, Altaïr was stopped by two guards. Altaïr located a nearby bomb supply. Altaïr lit the bomb and ran. With the guards distracted, Altaïr sneaked into the next area. Altaïr hid behind a large boulder, taking notice of the nearby catapult. Altaïr tinkered with the catapult, causing it to malfunction and kill the nearby guards. After hiding from the approaching guards, Altaïr made his way further into the camp. Altaïr killed the scholar and put on his robes. Blending with the scholars, Altaïr made it further into the camp, stopping at a weapons depot. Altaïr silently killed the surrounding guards and approached the weapons cache. Altaïr pushed the door open and entered the depot. Altaïr ignited a bomb and left. With the guards distract, Altaïr made his way to the next part of the camp. Altaïr approached a Templar guarding a cage. Altaïr pickpocketed the key and returned to the Templar. Approaching another gate, Altaïr was stopped by more guards. Altaïr accessed the tent through a side entrance, where he found imprisoned Saracens being questioned by a Templar. Altaïr assassinated the Templar. The Saracen died before he could finish his sentence. Altaïr freed the Saracens, granting him the diversion he needed to enter the next area. Altaïr left the tent and entered the next area of the camp. Altaïr killed a nearby crossbowman and armed himself, starting to fire at the soldiers. After shooting all the soldiers, Altaïr continued through the camp. Using the tents as cover, Altaïr made his way closer to the commander's location. Altaïr killed the remaining Templar and entered the camp's final area. Altaïr climbed to the top of the building the commander was on. Altaïr killed the commander and hid within the building. Altaïr ran to the catapult. As the guards approached, Altaïr set up the catapult and launched himself out of the camp.

 * Woman: Thank you for saving us!
 * Guard: He's here, corner him! Call for reinforcements! Curse you, Assassin!
 * Altaïr: If I release that lever, the box will fall...
 * Guard: Not so fast, Assassin! You'll never get past us!
 * Altaïr: This is going to be one tough jump... I must cross the city to their camp and stop their leader.
 * Templar: Who dares to stand against the might of the Templars? Who has the courage to cross blades with us? Assassin... Stand back, you two! He's all mine!
 * Saracen: Quickly, bar the gates! Don't let them get through!
 * Crusader: Attack! Destroy anything that moves!
 * Altaïr: They just keep on coming... I must find a way to block this gate... I could use this catapult!
 * Altaïr: They're coming over the wall... I should take out their observers. That should stall them...
 * Crusader: Attack! Destroy anything that moves!
 * Altaïr: Those ballistas are loaded! I should use them!
 * Altaïr: I think I can pick off that executioner with my crossbow!
 * Altaïr: I'll have to get past that soldier... To get to that rooftop... But I'll need some knives to take him down...
 * Altaïr: Those soldiers have taken that woman prisoner! They're only three... I can easily take them!

 * Archer: Crossbowmen, take aim! Fire!

 * Saracen 1: Defend the city!
 * Crusader: Destroy them! Sweep anything that moves!
 * Altaïr: It's pointless to fight them all!''
 * Saracen: Stop, Assassin!
 * Altaïr: I should leave the city and head for their camp!
 * Crusader: Don't let him get to the ballistas!
 * Altaïr: And now, to enter the Templars' camp!
 * Guard: Halt, stranger! We have orders not to let anyone pass! And to disarm all civilians... Hand us your weapons!
 * Altaïr: Alright.
 * Guard: Now turn around and leave this area!
 * Altaïr: Maybe if I disguise myself as one of the Templars...I could enter their camp. That soldier looks easy to fool!
 * Altaïr: Now I can enter their camp!
 * Guard 1: Stop wasting time, get about your business!
 * Guard 2: How long until Acre falls?
 * Guard 3: I reckon it'll be over by morning. They don't stand a chance...
 * Guard 4: End of watch, eh? Get in!
 * Guard 5: No wall can withstand our siege weapons!
 * Guard: Wait, soldier! You know the likes of you aren't allowed beyond these gates!
 * Altaïr: I could pass if I distract them somehow!
 * Altaïr: A bit of fire should do the trick!
 * Guard: Fire! Fire! The camp is on fire! Get help! Put out the flames!
 * Altaïr: These clothes won't help me in this area... I must remain hidden! More soldiers are coming! I should hide quickly!
 * Altaïr: I could tamper with that trebuchet... The guards mustn't see me, though...
 * Altaïr: Better leave, now... More guards will come!
 * Altaïr: This area is crawling with soldiers... And it looks like only the scholars can pass through that gate! One of them has left the group... I should get his clothes... That is, if I could get past those soldiers!
 * Altaïr: More siege weapons... I must destroy them, or the city won't stand a chance! But how can I get rid of those guards? I should attack them when they're alone!
 * Guard 1: Our camp is well protected...
 * Guard 2: I've heard Saladin's army marches this way!
 * Altaïr: Hmm... That door is locked!
 * Altaïr: A bit of fire should do the trick!
 * Altaïr: Better leave, now... More guards will come!
 * Guard: Fire! Fire! The camp is on fire!
 * Altaïr: The morning is getting close. They will start poisoning soon. I must find their commander before he can issue the order! I'll have to take him out!
 * Templar: Hold it there, scholar! You're not allowed to pass beyond this point! ...But I could look the other way for a moment... In return for a favor! I need the key to this cage here! A torturer has it... Back where you came from! Get me that key, and you may pass!
 * Altaïr: Here is your key!
 * Templar: Well done, scholar! You may pass! Girl, let's get you out of there!
 * Guard: Stop, scholar! You may not enter!
 * Altaïr: I need to distract them somehow... I'm sure I'll find something in that large tent... I must sneak in there!
 * Templar: Tell me: Where is it?
 * Saracen: Your garrison transported it! You must know!
 * Templar: I'll ask you one last time: Where is it?
 * Saracen: Stranger... come here! A great treasure... Lies buried... Behind the... Behind the... Arghh...
 * Altaïr: Where? Where is it? Oh well... I still need a diversion! Releasing the prisoners should do it!
 * Altaïr: Go! Now!
 * Guard: The prisoners are escaping! After them!
 * Altaïr: The path should be clear now...
 * Altaïr: Another trebuchet firing! I must stop it! But there are too many soldiers... Maybe with a crossbow... I could take them out from a distance!
 * Guard: What was that? Who did that? There! That scholar is firing at us!
 * Altaïr: More guards! I could sneak past them! They won't see me behind those tents...
 * Templar: All guards listen carefully! The captain summons you all to him. Make haste, all of you!
 * Altaïr: This is my chance! There's only one guard left!
 * Commander: My captains! It is with pride that I stand before you now! The reason you've all been summoned here must be clear by now! Acre's outer defenses have been vanquished! It's time to enter the city with full arms! Everyone! Await my orders and prepare for battle! Scholar! Yes, you! Come up here and give me your blessing!
 * Altaïr: But of course, my child! You'll receive yours right away!
 * Commander: Scholar, this is it! I sense that our victory is at hand!
 * Altaïr: You couldn't be more... Mistaken!
 * Commander: Guards! Attack the intruder!
 * Guard: Search every tent! He's been seen in this area! He was dressed as a scholar, keep your eyes open!
 * Altaïr: My mission here is complete! I should leave this camp as quickly as possible! But the exits are blocked... That catapult is already armed! I wonder if...
 * Templar: We've got you cornered! Where will you run now!?
 * Altaïr: Not yet, Templar!''
 * Altaïr: Whaaaaaaa!

Outcome
