Sneaky System 2.0 has been released, featuring a full rewrite of HIDE, SNEAK, SEARCH, and STEAL as well as two new commands: WATCH and POINT (as it applies to people whom your character knows is hiding).
WATCH gives you a very strong bonus to noticing a particular person hiding and POINT will let you reveal the hiding location of someone who you've noticed hiding, sneaking, or stealing.
Everything has been completely rebalanced to make sure that the system is fair and easy to use.
