Since AC 2 you can killed two guards in air assassination. In Unity and Origins you need a skill.
You can if you make a quick wall jump on a near target, when you are above them when you grab a wall or jump from a small building.
It's an Assassin's creed game. By the story, the gameplay and the construction of the game: a hero who need to assassinate many targets and foiled their plot on the political level and recovered an ancient artifact to save civilians. We don't play an "Assassin" in Origins, but in AC2 and Black Flag, Ezio and Edward were not Assassins until the very end of the story, but the games are considered as the best of the series. I think they complained about the fact there are more fights and no stealth, but the game is also more difficult and challenging, so when you are detected, it not easy as before to take down the guards.
The maximum level is 100 now.
It depends on what you like. There is critics about AC OD is that it more fantasy than other AC and less historical, which I found a little unfair as there are a historical arc and a "mythological" arc in the story. Personally, I played every AC games and I like it. In gameplay, it's like Origins, but the stealth gameplay is a bit frustrating at the beginning as you are low level (but I first played in hard mode, so maybe it's easier to assassinate). There is more fighting than in Origins and the power gives some variety but sometimes it feels a bit smash multiple times the button to kill the enemies (but I play in the hard mode, so...). The naval battles are fun but also difficult if you are not prepared. If you like the AC lore, it will depend: some find it breaks the lore but I don't find information that denied previous pieces of information in precedent games.
@Jasprit Singh187 Sorry to be rude, but what you said about the Master Assassins is wrong. Altaïr became a master Assassin after saving Al Mualim in 1189 from the traitor Haras and later recovered it during the Hunt of the Nine. Ezio became a Master Assassin between 1488 and 1493 as in A War in the Shadows, they refered him as Master Assassin. As Shao Jun was the last Assassin in China, she automaticly became the Mentor of the Broterhood. Arno reached the rank of Master but he wasn't confirmed as a Mentor.
I think that an Assassin became a Master when it accomplished a difficult mission and proved its loyalty to the Brotherhood. Maybe the number of years it served the Brotherhood also count.
The DLC occured after the main story so, finish the Sequence 12 and after you could lay the DLC.
I think it's a little simplify. For me, Assassins are more for Democracy, as Demos=people, the well-being of the people and their choices must be respected, with the first tenet of the Creed and the Maxim. The Assassins could accept any forms of government (Empire, Kingdom, republic) if they respected the civilians. At the extreme point, if they killed anyone who opposed them, they are fascists.
The Templars are more for an Aristocracy, as Aristos=the best, they think that the most educated (them) must rule the world to prevent war. At the extreme point, if they control everything, they became fascists, as they want that any citizen thinks like them.
Sometime Templars are for social change, as slavery which is considered as inhuman by Torres. And some Assassins are for conservatory power, as Mirabeau who wanted to preserve French Monarchy and calm the Revolution.
