I have to use at least 3-4 health pack just to kill one.
Taking pictures can be a chore too, and sometimes it's difficult to know which one to take, since they look alike...
If you play with Vita chambers you can´t loose ;).
It´s not hard you will just need to learn to use what tonic and when. I remember I don´t remember what Bioshock there was a boss where I didn´t figure out what tonic to use. Incredibly hard but once getting the right tonic ridiculously easy instead lol.
Try System Shock 2 for more of a survivor horror feel.
I will say you can safely jump the DLC for infinite. Do not buy.
System Shock 2 is still to this day the game that had the biggest impact on me.... Late 90's.... a decent sound card and headphones in a dark room playing late at night. It was a truly suspenseful and terrifying game... One of the first, imo, to really convey that via the ever evolving 'multimedia' capabilities of the PC! There were times I'd actually have to leave the room and calm myself down as I got so engrossed in the gameplay. I'd go to bed freaked! Great times!
I do love the BioShock series too... the first one in particular but I have a super soft spot for SS2.... Y'know I still have the original with full retail packaging in perfect condition - something of a memento for me!
