Dishonored delivers as the king of Stealth Action video games as a result of the freedom it gives its players. The game appeals to veteran stealth players and those with a lust for action alike. As ex-Royal Bodyguard Corvo Attano you are given the rooftops, streets, alleys and sewers of Dunwall to roam across levels, making your way to your target, either avoiding enemies or killing them all along the way. Where this game really shines lies within the fact that your playstyle isn't pre-dictated by the game. Although the game would have you believe (what with all the weapons, gadgets and supernatural powers at your disposal) that your aim is to massacre anyone that gets in your way, you can, as I myself did, finish the game undetected, without killing a single person, including your key targets whom you may remove by other means. In the same playthrough I managed to finish the game on the highest difficulty, undetected, adopting a non-lethal approach and not buying a single power other than the default short range teleportation, 'Blink' (granted I did each of these for achievements) but the fact of the matter is you may go about the entire game in any way you desire.
The art style is unique, with the game adopting a Steampunk-esque style that plasters the map, with the dark greys and blacks harking to an era in time influenced by the industrial revolution. The game is lengthy enough to not leave you feeling cut short, but not so long as to allow your attention to wander, and each mission includes a high level of replayablility, whereby on your second time round you can explore alternate routes to your goals, or try different tactics.
My one gripe concerning this title would be that Daud, the character whom two of the three DLCs centers around, is a more interesting character overall, be that because he has a voice (unlike Corvo) or alternate powers and gadgets. This brings me to my next point; Downloadable Content. Dishonored features three main DLCs, in two of which ('The Knife of Dunwall' and 'The Brigmore Witches') you assume the role of the aforementioned Daud, whom you will encounter in the base game's story, as he embarks on his own quest for redemption. These two story expansions are beautifully designed plot-wise and level-wise and do not feel like rushed cash-grabs on Bethesda's behalf. Playing through them allows a greater insight into the story of Dishonored and in my opinion they should not be cast aside. The third main DLC, 'The Dunwall City Trials' seems less of a necessity story-wise and brings only some arcade style game modes to Dishonored, centering around time trials, arena battles and stealth missions.
If you are considering buying this game I personally would recommend the Game of The Year Edition over the Regular Edition, as it is highly likely that it will save you money in the long run. The base game is compelling enough and features a large amount of replayability, but when you do come to wanting more, 'The Knife of Dunwall' and 'The Brigmore Witches' are more than worth your money and time.
The game is almost always on sale along with the GoTY (Game of the Year) Edition, and if you're unsure about whether to buy this game, or you're just looking for something new to play, I can highly recommend Dishonored as being one of my favorite games to this day and the chances are if you purchase this game you won't regret it.
