Tougher Enemies. Better AI
You've already heard about the new baddies of Rapture - Big Sister, Rumbler Big Daddy and Brute Splicer. But what about the underwater city's previous inhabitants? The Al has significantly improved, making these Splicers faster, stronger, and smarter than before.
The new, larger levels often span multiple floors, giving Splicers plenty of cover, which they put to good use. Thuggish and Leadhead Splicers attack in droves, while Spider Splicers throw blades in rapid succession as they scurry in and out of surrounding vents. Now that more levels span multiple floors, Splicers attack from all directions so it's crucial to make good use of the Hack Tool to get your surroundings to work in your favor.
