Easy Money
In Shadowrun, there are lots of devious ways to earn extra money... here are a few of them:
Join the Mafia and polish your reputation and negotiation skills. Using your discount at the Mafia's Crime Mall, buy light combat armor and sell it for a profit!
As a Decker, get a job for a cyber run. Then, go to downtown Seattle - the lower left-hand corner - where there is a building and a vid-phone. Using the phone, hack into your employer's network and download as many files as you can. Then go into the building and sell the files! (Note: The buyer will give you what he thinks the files are worth.)
