i liked the idea.. but to have them in practicly every room you entered really slowed the game down. And it was always for a handful of credits or some xp. But as for hacking doors, like when you sabotage the Mech prior to going after Archangel, was good. The idea was good.. but to do the same memory hacking time after time after time again just made them frustrating. Its not like they were challenging or anything.
