We might get Gar to write about the GUMSHOE and Fear Itself implications of the great Netflix series "Stranger Things" soon. Before that happens I’d like to sneak in to highlight one particular moment. Without delving too far into spoilers for those who have yet to binge, a point comes where rumpled police chief Jim Hopper (David Harbour) needs to get information on the other side of a guarded door. As seasoned GUMSHOE hands know, if you have the Locksmith ability and a locked door stands between the PC and that info, the PC gets the info, no spend required. Here we have a classic example of that setup, except that it’s a uniformed stooge of the evil conspiracy and not a lock. What does our hero do? He knocks the guy out with a surprise shot to the jaw, opens the door, and heads on in.
This brings us to an obvious extrapolation: in GUMSHOE, you ought to be able to do the same.
I’d restrict this to characters the tactic feels right for. If your investigator has the investigative ability Intimidation and at least 4 points in Scuffling (or the equivalent, depending on which GUMSHOE iteration you’re using), you can KO a guard to get a core clue. In certain GUMSHOE games you could describe this in different ways: using a stun pistol in Ashen Stars, a Concussion blast in Mutant City Blues.
Hopper suffers no direct repercussions for knocking out the guard. It never gets mentioned again, in fact. We must assume then that he spent a point of Intimidation to ensure that he not only got the clue but did not suffer any blowback for resorting to the rough stuff.
When building or improvising scenarios where punching your way to information, you might include the opportunity to stave off later consequences with a spend of Intimidation, Bureaucracy, Cop Talk, Credit Rating or whatever else seems appropriate to the setting. This might cost 1 point or even 2, if it would otherwise seem unlikely for the investigator to get away with this entirely.
Since you can’t count on a player to think of this fun but extreme solution, or for the punch-enthusiast among the party to be the one that shows up at the door, also allow a more typical alternate way of getting past the guard.
