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.)
Free Cab Rides
To ride cabs free, garner a good reputation. Then go to the Ork gang hideout and buy protection from them. The "smell" cloth they give you in return can also be used for free cab rides!
Free Upgrades
If you're short on cash but desperately need to upgrade your weapons, ammo, or other items, hire a runner who you don't particularly like. Take all of his items and kill him off. Viola!
Join Mafia
To join the Mafia, go to the Eye-Fivers' hideout in the Penumbra district and talk to the gang's boss. Pay him off and he will give you the number to Mr. Faradouchi, Mafia Don.
Join Yakuza
To join the Yakuza, go to the Hallowneers' hideout in the Redmond Barrens district and talk to the gang's boss. Pay him off and he will give you the number to Agira Tetsumi, Yakuza kingpin.
Strange Glitch Of A Guy Getting Run Over
Go to the Redmond Barrens and go see the Eye-Fivers and talk to their boss. Get the phone number and call it on the vid-phone. Then when it comes on hold the key pad up. Hold it for about twenty seconds and then you will not see a picture of the man you want to talk to. You will see a very graphic picture of a dead man being ran over. The game might freeze after this code.
Unlimited Bullets
Buy any type of grenade when you have the money, but DON'T EQUIP IT. When the bullets in your clip get down to about 3-5, equip the grenade then switch back to the gun you're using. You may have to do this more than once to get back to a full clip.
Unlimited Clips
Hire a shadowrunner. Buy 20 clips for yourself, then trade them to your 'runner. Buy 20 more clips and then trade them to your shadowrunner again. Repeat the process as many times as you like then have your shadowrunner trade them.
Unlimited Life
For infinite lives, press A, A, C + LEFT, B, A, C, RIGHT, UP, DOWN + LEFT at the title screen.
