Awesome interview with Ken Levine (spoilers).ATM I'm half way through it. Just been playing it a bit here and there. Been busy. I really enjoy it so far. I'm at Fort Frolic. Things seem to be getting even more interesting in this level.
The story is really good. If I said anything negative about the game it would be that there is almost too much atmosphere. hehe
You can almost piece together the story before the end if you pick up on the signs, recordings and other hints woven in there (i've read some spoilers). Easy to get a good idea of what happened before you arrived in Rapture anyway. If you like single player games that have a solid story then pick it up. Definitely one of those big SP titles that come every few years.
I've been playing on hard and it really is hard. Enemies have more health and I really noticed a resource crunch (ammo, evo for plasmids). Gotta really play smart then. Turn the enemies on each other or use telekinesis to pick up big objects for blocking bullets and throwing at enemies, use the right bullets for the right enemies (regular,armor piercing, antipersonnel). I hack all the turrets and security cameras/bots I can. They are a big help since they will then attack enemies and not you. Hacking vaults is tricky but usually worth it even if you mess up and get hurt.
I might need to go to medium to finish though.
It's really fun when a big daddy is in the area. They don't hurt you unless you make yourself a threat. But you can pit them against other bad guys. Gets the big daddies health down a bit too. Then you can take him out and get some Adam from the little sister. (You have to choose rescue, not harvest, with
all the little sisters to get the 'good' ending.)
