Don't take the "5" I've given here as a bad score. I would attribute this score to an average, middle of the road game which is exactly how I feel about Lords of Shadows 2.
After playing the original LoS, I was looking forward to the sequel. LoS was a good game and a nice "reinvention" of the Castlevania formula, the first good one I've played in 3D. Unfortunately, the developers of LoS2 chose to add a few elements to this game which drag it down, causing frustration and annoyance throughout.
First, the graphics are beautiful, and this is coming from someone who has played Ryse etc. on Xbox One. LoS2 is definitely one of the best looking games on Xbox 360, it really is eye candy. The game runs smoothly and the combat is (generally) fun, with a few minor blips that come up from time to time. The story is a direct continuation from LoS, and if you're into the Castlevania lore/story, you'll probably like this.
As for the rest of the game...there's nothing broken here, but there are some serious design flaws which caused me a good deal of annoyance as I played through the game. In particular, the stealth areas really ruin the pacing of the game and can be frustrating areas of trial/failure. Navigation, platforming, and climbing can also be annoying due to the camera which can get downright stupid at times. Some enemy encounters feel cheap at times as well, and the checkpoint system can definitely use some work.
Overall, not a bad game. It's decent, but don't go in expecting the same quality or fun you experienced with the original.
For the most part, I enjoyed the game - good length of play, graphics pretty good, gameplay easy (though with zillions of combos, I find myself sticking to half a dozen or so throughout)...but the travel in this game, from location to location, was extremely trying on my patience and memory. I hate resorting to online maps and guides to find things, but there was nothing intuitive or easy to navigate with in this game. Just trying to get back to the Chupacabra's Shop was the insanity that made me put this game back in the mail to Gamefly. I wanted to round out the items and level everything up after the main storyline was finished - but it was so horrible to travel all over the place to do it, I just gave up.
I guess regarding storyline, I just don't know my Castlevania history as well as I thought I did - I don't remember all the characters involved, if they did exist. If they were new for this game, there was no real explanation for who they were or where they came from. The ending tried to tie it all up, but didn't really pull it off. Still, worth playing in my book.
