A change of pace in the Clancy genre.
Reviews seem to have a trend with the bottom line being the "game is too hard".
Had trouble at first but if you pace yourself and advance with sneaking as a priority, leveling up and making progress gets much easier. Solo or in a squad.
Once you understand the enemy and objectives, it gets so much better.
Definitely worth it so don't let the people having trouble concentrating sway your interest.
