Just out of curiosity, where in Houston? I'm looking to get into 6th

Things to bring: reference sheets. Simple stuff, at least for the first session, like sample actions and related dice pools for combat, social, magic, and matrix. An intro session could cover all or even just one of these, but a quick reference for possible options (just a couple, not exhaustive) can really help players unfamiliar with the game make quick decisions.
One-shot suggestion for a black trenchcoat run:
Players are hired as a red-team to test the physical/matrix/magical security of one of their facilities. They have 7 days to case and prep, and payment depends on how many objectives are carried out and whether they are discovered or not.
Sample objectives:
1. Retrieve an object from a certain location, such as a document from a safe in the managers office or a prototype commlink from the research lab; requires physical access, so could be performed through stealth infiltration, covert incapacitation (stun only!), or social infiltration
2. Obtain documents containing falsified research data; could be matrix run, or physical/social infiltration
3. Plant a dual-natured object in an obviously warded area; would require magical support
All of these could be used to introduce concepts common to the setting. Sneaking, hacking, social interactions, stealth combat, legwork, you name it. There is also enough diversity that almost any character would have time to shine.
If the party is combat heavy, make the run itself a short one and have Mr Johnson betray the team in classic fashion. Let the runners Duke it out with personal security.
