Arriving in the Borgia-occupied settlement, Ezio sought the engineer. Though he located the man in the outskirts of the fortress, he was protected by a bodyguard, preventing the Assassin from extracting any information from him. Thus, he tailed the pair from behind, listening to his target converse with his guard, regarding the machine's safety.
- 保镖: 发明有卫兵把守，我把密探关起来了。
- 工程师: 试图窃取切萨雷东西的人必须受到惩罚。
As the engineer entered the heavily guarded factory, Ezio quickly took an alternative route up the eastern walls, passing through a damaged section. Dropping down to where the engineer was standing, he confronted him.
- 工程师: 你想干嘛？
- 埃齐奥: 武器设计图在哪里？
- 工程师: 在堡垒另一端的桌子上。
- 埃齐奥: 那实物呢？
- 工程师: 我不清楚，但要三个人才能使用。
- 埃齐奥: 那你跟我来。
- 工程师: 不！我们……我们俘虏了三个士兵，他们被关在设计图对面的牢房里。他们会帮你操作的。
- 埃齐奥: Bene.（好。）
Ezio allowed the engineer to escape, and proceeded to make his way to the opposite end of the factory. Finding the plans at a small workshop, Ezio burned them using a torch, and made his way to the captured mercenaries. Dispatching the patrolling guard, Ezio asked the mercenaries where Leonardo's machine was hidden.
- 埃齐奥: 达·芬奇的机器在哪？
- 炮手: 跟着我们！他们把通道藏起来了，但我们找到了入口。
The Assassin freed and followed the men, however, they were ambushed twice by a large number of Borgia soldiers. Despite this, Ezio and the mercenaries eventually overpowered them and proceeded.
Once led to the entrance to a network of underground tunnels, one of the mercenaries commented on what Cesare planned with the tanks.
- 队长: 切萨雷打算把它作为军队的核心。他的军队准备突袭西西里岛。
- 埃齐奥: 我们会阻止他们的。
Descending underground, the trio came across a long, but narrow passageway. Restricted by gates, Ezio volunteered to find a solution so they could progress.
- 炮手: 我们需要打开那扇门。
- 埃齐奥: 我会想办法的。
Ezio opened the gate, and then found a way to the second lever.
- 炮手: 终于见到你了。
- 埃齐奥: 别考验我的耐心。
Ezio and the mercenaries discovered a raised bridge.
- 埃齐奥: 我会把桥放下来的。
After winding a lever to help the mercenaries pass, the Assassin and the two men came across the Tank.
- 埃齐奥: 莱昂纳多要我操作这个？跟往常一样，没有说明书。
Ezio and his new allies took control of the war machine and staged a direct assault against the main weapons factory.
- 警卫: 不要再守着它了，向它开火！
Easily plowing through the countryside with the powerful weapon, they fired upon any mounted cannons, foot soldiers or other tank prototypes that blocked their path.
- 埃齐奥: 如果我们的能受到伤害，他们的也能。
- 队长: 再来几炮！
Blowing the gates of the main factory open and entering the courtyard, they discovered several damaged siege towers, and cannons in the process of being repaired, as well as several working or half-built tanks.
- 队长: 你把切萨雷的军队打得落花流水！
After having destroying the other war machines and siege weapons within the fortress walls unscathed, the mercenaries took their leave, while Ezio climbed up to one of the buttresses of the factory and stared down at the Tank.
- 埃齐奥: 我真希望能留下你。
- While using the Tank, Agile guards could be seen using arquebuses, trying to shoot at Ezio; the Tank would receive no damage and the guards would soon flee if Ezio opened fire on them.
- Although the engineer mentioned three mercenaries, the third was injured and left in the cage. At the end, the mercenaries that accompanied Ezio seemed to leave in the opposite direction from where the Borgia fortress was – therefore leaving the injured mercenary behind. This might have been an oversight.
- During the final segment of the memory, in which Ezio had to destroy two Tanks, retreating just behind the Animus Wall would make it impossible for the Tanks to shoot him.
