a bunch of info on the upcoming Wii U version
So, what changes have been made? Top of everyone's list, Deus Ex executive game director Jean-Francois Dugas and game designer Emile Pedneault tell Eurogamer, were the boss battles.
Deus Ex's boss battles are considered by many to be the weakest part of the game. They were frustrating, combat heavy fights that broke Deus Ex's sneaky heart, forcing players to fire guns pathetically after they'd popped all their upgrade points into stealth and hacking. In short, the boss battles were a bit crap, and it came as no surprise when it was revealed that their development had, in fact, been outsourced.
"We went through all the boss battles and said, 'let's just start from the beginning,'" Pedneault says. "So that's exactly what we did."
Each of the game's three boss fights have had their map layouts reworked to provide players with alternative potential strategies. New hacking challenges are available to players who focus on hacking, and stealth options are available to those who focus on stealth.
POTENTIAL SPOILERS AHEAD:
I may have to do a double dip on this, although it would be awesome if they brought some of the changes over to the PC (and other consoles I guess).
