Finished the DLC & Secret Locations. Was not very good afterall.
It's a lot of content. Took me about 4 hours for all of it combined. But it's like 4 hours of the lowest quality AC2 gameplay and that is kind of fun for an hour or two but overstays its welcome.
The 2nd DLC with the new section in Florence is weird. The section only has 1 unique looking area and 6 viewpoints. There are no treasures and no feathers, so there's little incentive to explore. Half the new missions don't even take place in the new area of Florence and instead are just in the main city. It's basically just "hey, go kill these 9 people spread out in the city" and each kill mission has a 15 second cutscene and 15 second death talk after you kill the guy. Some of them are a little creative, but what KILLS about half of them is there are "kill the person without being spotted while always in max notoriety and we're putting the people in really hard to get to spots so you can't cheap shot them". It's fun but having it desynch and load and start you over anytime anyone spots you gets tiresome. For 1 guy it's ok. But then when you finally kill the guy and you get to do the same thing for FOUR MORE GUYS, it's kind *groaaan* There's not much plot in the 2nd DLC either.
The hidden locations were a mixed bag. The Florence one was ok, nothing great, nothing terrible. Just a little platforming, a little kill guys. The boat aresenal one in Venice was kinda lame, and the other one in Venice was just another ubi singapore church linear platforming with checkpoints which was good fun but still easy.
I really don't think anyone who doesn't play the DLC is missing out out anything. It was okkkkk and enough content for $10, but the quality of the content was pretty mediocre. Better to put that money towards AC2-2 and ROME (with hopefully good mission design).
On the plus side the DLC finally gave me a reason to start using the pistol since it made some of the really annoying kills, just slightly annoying insead.
