Your hero can sense when something bad is about to happen. Anytime he’s about to be the victim of a surprise attack, ambush, or other nasty surprise, he gets a Notice roll at -2 just before the attack or event occurs. If successful, the character knows something is about to happen and may take appropriate action against it. This means the hero is on Hold for the first round of a combat.
Should the hero fail his roll, he still follows the normal Surprise rules, if applicable.
