Assassins creed brotherhood is the first game that i played from the assassin creed game series but it is the third game in the series. The game was unique in terms of game-play from other games out there. Most of the tasks in this game require you to kill a particular person because they were somehow linked with your father's and brothers death. After playing this game, i was compelled to play the upcoming games in assassins creed series. All of them were planned and executed. I love those missions in this game in which you have to silently kill a person like in Hitman games using stealth and crouching. 

In the game, one good tactic to save yourself from enemies or just avoiding getting into combat is to merge into large crowds that can be found throughout the game-play setting. The sprinting system in the game is amazing; i love how while sprinting you can climb walls and this system kinda resembles the system in Prince of Persia games. 
If you are looking for some different game but full of action, adventure and beautiful scenes then you should consider playing this game because it provides that adrenaline a gamer wishes for.
