Dishonored is a true memorable game. It does everything right.
You have a diverse arsenal of weapons and powers at your disposal in your story of revenge.
As Corvo Attano, you put the mask of an assassin in a city tormented by chaos. Your way of dealing with problems will influence the city, since killing will take chaos to new levels or being a pacifist will get you a happy ending.
Level design is well thought, so being the good guy is not impossible but rewarding, while being the bad guy is really fun. The chaotic play style is the one where you'll fully enjoy your ablities and their upgrades, but as you progress that way, things get harder, as the game adapts to you to be challenging. Assassinating your targets is fun, but handling things peacefully is actually more attractive, as you'll deal with fascinating NPC's . If you'll take your time to explore, you'll get to know an engrossing world. Overall, this game is a gem that deserves everyone's attention and while it is kind of short but has a lot of replay value and with the GOTY edition you have a lot of content to play with
the score of 9.8 does it justice.
You can get this game cheaply with dishonored 2 LIMITED edition for the difference of only 3 pound!
