I found it to be more like a modern Assassin's Creed, with hacking/profiling instead of eagle vision/triggering traps, instead of scaling buildings you transmit through/round them.
Depends how you play, stealth is very AC (don't get spotted/distract), but you can run & gun like GTA (take everyone down before the cops arrive)for some of the missions.
Just finished the campaign and enjoyed it (not posting any spoilers) :thumbup:
