The multitude of different skills the characters have makes stealth clearing a scenario quite creative. There are many different ways to go about it. It can be slow with many save/retry cycles but the payoff of finally braking an area is very satisfying. I find it very difficult on the beginner/easy setting, but only 1 scenario (where they lost all their equipment) had me frustrated and wanting it even easier. All in all I enjoyed this game very much.
