Both ways folks, both ways. I'd rather the local authorities have a very capable stunner to rely on so they don't use deadly force on my characters comrades when they get out of line (My characters never get into trouble!).
Sleeping gas grenades, tranquilizer darts, chloroform, all of these are legitimate ways of knocking someone out and then having your way with them. Don't see why there is an uproar about stunners.
Perhaps you are equating them to technology you are familiar with? The stunners are TL8 or better - this is future technology. Our current technology, according to the book, is between TL7 and TL8. Think of the very best stun weapon currently being designed in a test facility today, and these military/law enforcement grade stunners are specifically designed to knock out its target, not just temporarily immobilize them.
Possabilities:
- Perhaps in YTU you adjust the law level for restricting stun weapons because too many citizens use them on each other for robbery, rape, or just controlling their unruly children.
- For less effective stunners
1) Adjust the Endurance roll to Must roll over the amount of 'damage' (after armor is subtracted) using an End DM.
2) Stun 'damage' goes to Endurance (Tracked separate from regular damage). An endurance check is only needed if you sustain stun 'damage' which brings your endurance down to 0. Repeated successful attempts to stun have cumulative 'damage'. Possible -1 DM for each round stunned.
3) Make the endurance check routine (+2DM) instead of average. Possibly adjust the difficulty of the check based on the TL of the weapon.
4) Give different types of armor a DM against stunners.
Regaining Consciousness. This is an endurance check (and endurance would be at normal level since stun 'damage' is ignored). Normally you can't do this check for 1 minute, which is 10 rounds. you could however:
1) rule that an immediate check can be made if certain things are done to the stunned individual. Possibilities: smelling salts, adrenalin injection
2) if unconsciousness was caused by a stun weapon, allow the check to occure after X number of rounds. You decide what X is. You can get complicated here by using the effect of the stun attack, the persons Endurance, and so on as modifiers to X.
3) The Unconsciousness endurance check occurs after 10-60 seconds, roll 1d6 to see how many 10 second increments.
4) The Unconsciousness endurance check can occur sooner similar to going faster/slower and the time frames on page 50. Instead of a average check after 1 minute, do a difficult check after 6 seconds (one round) and every 6 seconds after, if it fails.
As usual, these are just some thoughts for you to ponder and I have not play tested it. My personal preference is to not modify the rules and only create house rules for things that are not covered.
