[HoE] I need help with a scene

[Thomas Mayfield <dragonboyblue@mindspring.com>]

SPOILERS (Jack, Zack- scram)




















I'm planning an adventure, and need a little advice on how to handle on
particular part.My posse consists of a junker (no browser), a former
assassin syker, a tough biker, and a SOB gunslinger.  The posse is going to
be hired by a junker merchant to retrieve a security access card to a
dormant ghost rock reactor.  Now, the posse will only they are being paid
very well to go after a "red card with Hellstrome Industries and many
numbers" on it.  I'm toying with the idea of making the card a relic, too.
Anyway, they track the thieves to the ruins of Sacramento, and hopefully
get the card back by guile or force.  Now, here's what I need help with:
When the return to get their payment, the junker will betray the posse to
the Cult O' Doom who desperately want the card to increase their power.
How should I handle the scene where the posse is betrayed?

Thank in advance,
