This is not a game I could just get right into because of all the info I needed and wanted to put in having the Signature Edition. Outside of those, entering a code to unlock multiplayer was annoying. I understand the reasoning behind it but it's obnoxious.
The game picks up from Brotherhood when Desmond fell into a coma after stabbing Lucy in the stomach. In Revelations, Desmond wakes up in an island world with broken fragments of stones in sand, water and in the air. I quickly learn that Lucy does not survive the stabbing and the team is wondering if Desmond is a Templar.
Desmond finally meets Subject 16 who's stay in the Animus has turned him into a lunatic as they he talks to Desmond and his perspective. The area Desmond is in is now the new overworld--Animus Island. It's a part of the Animus and part of Desmond's subconscious. The Animus is what is keeping Desmond alive at this point but if Desmond doesn't come out, he will end up like Subject 16.
Entering Ezio's memories are as simple as running through a giant, glowing door. From there, it's Assassin's Creed as normal with Ezio Auditore da Firenze as the hero. The game plays exactly like Brotherhood. There aren't many changes until he get your first upgrade, the Hookblade. The Hookblade allos you to traverse rooftops by hooking onto ropes that the people of Constantinople have set up.
I travel around with another Master Assassin, Yusuf. However, every calls you "Mentor." Ezio is the most talked about Master Assassin in the European region but similar to Brotherhood, my time so far has all been in Constantinople. The city is beautiful. The light orange glow given to the art gives Constantinople a feeling of old but also a feeling of grand.
Yusuf is a fun guy who does not take himself very seriously but has a heart to save Constantinople and make sure the Assassin order remains in tact. The personality differences between Yusuf and Ezio is entertaining as Yusuf is constantly clowning. The relationship makes Ezio look stoic like Altair.
I've only played one mission with Altair so far and it was short. It was a flashback to when he was 24 and the Templars raided Masayaf. It shed some light into how Al Mualim became fond of Altair and vice-versa. It makes it seem like Al Mualim did not start off with evil motives.
How did Ezio get to Constantinople? He's looking for five keys that Altair hid which reveal the truth. The truth about? I'm not sure yet. But apparently, Altair hid them in various parts of Constantinople. Ezio traveled to Msayaf (which is unfortunately, where Ezio's journey starts in the game) and tried to get into the library but he needs these keys and finds out that the Templars already have one.
Back to the hookblade, it allows you to execute a new getaway maneuver and it creates new execution style moves during combat. Speaking of combat, it's as smooth as ever although in the beginning of the game, the audio was noticeably slow to keep up with the action. That didn't remain forever.The combat is exactly the same as Brotherhood and there are no in-game tutorials to assist. However, there are tutorials that can be accessed during loading screens or when a new concept is presented by pressing the Back button.
The tutorials might come in handy in practicing launching bombs, a new equipment in the game. There are three types of bombs: Lethal, Tactical and Diversion bombs. And I have to collect the supplies to create the type of bombs that I want. Bomb crafting is very, very simple. The hard part is finding the necessary pieces to create them. Each type of bomb has three parts. I don't remember the exact name of the parts right now but the first one is the shell, the second is what affects the blast radius and the last determines what kind of bomb it is--lethal, tactical or diversion. The bombs are very useful and create new gameplay opportunities and ways to stay stealthy or be even deadlier.
Syncing challenges return although I don't really care about them. If I was a completionist, I would although maybe after I finish the game, I will try to 100% synch all the missions. Most of them require me to remain undetected which is difficult sometimes but it's made a little easier with bombs to help out.
Using the map is the same since AC2. What's annoying is the amount of clutter that can appear on the map and although you can turn all of it off, it doesn't save so the next time you play, you have to go through the menu's and turn everything off again.
The Borgia Tower concept returns in Revelations except Assassin's try to take over Templar Dens and use them for themselves. What is new about Revelations is Den Defense which is an RTS type of system where you can place Assassin in certain parts of a map to keep Templars out. Each wave of Templars gets increasingly more difficult. Assassin's have the ability to boost "morale" which are basically spending points to get more types of Assassin's like Rifleman Assassin's or Crossbow Assassin's and if you've gained enough Assassin's into the master ranks, you can send out Master Assassin's to replenish morale. It's a nice touch and it's a good break from the somewhat monotonous fetch quests that happen in the game. Unfortunately, when Templars try to take over your den, you cannot use the underground tunnels to transport yourself closer or else you will automatically lose the den. Constantinople is huge so this element seems pointless.
