One of the most amazing games i've ever played.(Minor spoilers.)
Gameplay: In Assassin's Creed, as the name states, you are an assassin during the Crusades, killing Templars for what you belive in. You take control of Altair, (there's supossed to be two dots over the I, in his name,) who disobeys his master, therefore is demoted to the lowest rank, and then has to work his way back up to the level of master assassin. To do so, your master gives you nine assassinations, which most are differnt, but some are very similar. Because of your assassin training, you know how to fight, climb bulidings, and jump, and basicly perform acrobatics. (You can't swim though.) The game is similar to Grand Theft Auto. You have a giant open world in which you can free roam around. There will be gaurds who will kill you if you provoke them, (like cops in GTA), and there will be many citizens. But rather than think that you can just cut through the citizens with one of your four and a half weopons,(sword, hidden blade, fists, throwing knives, and short sword counts as half a weopon.), you must follow the assassin creed.
1:You may not kill innocents(If you do, your health goes down.)
2:Stay hidden. (When guards aren't trying to kill you, you are hidden, and your health regenerates.)
3:Never compromise the Brotherhood
This dosn't get hard to not follow. As I said before, you have cool skills. Within fights, you can perform combos and such, and you acrobatics are cool. You can skale buldings by climbing up the windows. There is no building you can't climb.
Graphics:Amazing.
Controls:Really solid. It's hard at first, but there's a lengthly turtorial, so, you'll learn.
Sound/music: There isn't too much music to be heard, but when you do here it, it sounds amazing, and the sounds are also solid. The voice acting is also really just wonderful.
Replay value:High 9/10
Conclusion:Get this game. It can't afford to be missed.
