Assassin's creed 2 has undergone earth-shaking changes, and the degree of freedom has increased. You can buy weapons, armor, medicine, poison, etc.
Weapons have also increased, such as sleeve guns and poisonous blades. And you can also earn money by buying a store (how much will you pay every 20 minutes). The plot is the best of all AC.
Compared with 2, Assassin's Creed Brotherhood has not changed much. It has added crossbows, which can collect younger brothers, upgrade younger brothers and seize enemy territory.
Assassin's Creed's apocalypse weapon added hook blades, bombs and defensive towers (that is, you took territory from the enemy and the enemy could take it back in this way).
Assassin's Creed III has changed a lot, and its degree of freedom has improved. It added bows, muskets and tomahawks. You can climb walls, climb trees and hunt more smoothly, and there is a whole naval branch line (the naval battle is great), so you can change clothes.
Assassin's Creed 4 tells the story of pirates. The naval battle has been greatly improved. The new weapon is used to blow arrows and double knives. You can bring four muskets, find treasures according to the treasure map, upgrade ships, fish (sharks, whales, etc. ) and change clothes.
There is little difference between Assassin's Creed mutiny and 4, so you can collect Viking weapon sets.
Assassin's Creed Revolution, with many feeder lines, can customize clothes, the plot is not good, there is no naval battle, and the configuration is scary.
Compared with the Great Revolution, the architectural style of Xiong Xiong in Assassin's Creed has changed greatly, including wider streets, more floors and taller buildings. In order to cope with these changes, players can equip ropes from the assassin's armory to travel through the city more conveniently. The crowd will be confined to the sidewalk, and players can drive carriages. Trains and ships will also appear, but it is not clear whether they can be used as transportation.
Basically, it's all by hand. Hope to adopt.
