The story of Dishonered is something you can read on your own. Basically, you got screwed over and its time to kick some butt and get your revenge. You go through missions choosing how you want to do things. Do you want to walk through the front door and shoot every one? Or would you rather find another way inside and keep quiet.... Would you want to kill your target in front of people? Or do you want to lead them elsewhere? ....
The game is really fun in terms of freedom (this is not an open world game, mission wise it is not linear). You also have special powers, that's right. And as you collect these things called "runes", you can get even MORE cooler special powers. Like controlling people, or summoning a group of rats to eat people alive (FREAKIN' AWESOME). However, just like anything Dishonered has its negatives. For example, the story line just isn't that intense. You will find yourself skipping through dialogue because you just don't care. And there are certain things in the game that make you say "Oh.. well that doesn't seem right" for example you have a freaking heart that you carry around with you to find runes. Who the heck came up with that idea?
All in all, its a game that reaches new heights and really will grasp you... UNTIL you put it down for a couple of days. I was out of power from hurricane sandy and didn't get to play, but when I put the game back in a couple of days later - I found it super difficult to even get back into the game. It JUST doesn't grip the player for long. But if you put aside that and the sillyness in some aspects, you're going to have one EPIC adventure.
This was a game I was excited to get my hands on. It looked like it had a lot of promise. That's until I started playing. The graphics can shine, or just be pretty bland at best. It's as if they put effort into some areas but rushed through other parts (and it's noticeable). The game play is can be pretty slow at times and often, and it really doesn't require that much thinking. I would compare the play style to Deus Ex: Human Revolution, but slower and less polished. I really found the characters to be bland and forgettable for the most part. Even a lot of the side quests just really seemed like they could have been left out. Pretty quickly the game becomes repetitive and simple. The same actions take to take down enemies quickly and easily becomes boring and I found I quickly got bored trying to chug through the game.
It's worth the rent if there's nothing better on your list. You may enjoy the stealth games more than I do.
