Always check six.
If Mr. Johnson says it will be a milk run, always assume a trap.
It is easier to dodge questions than bullets. It is better to do a stretch inside than to get gunned down like a dog.
Leave that 'hero' drek on the trid where it belongs.
Sometimes you do the right thing. Sometimes you shoot people in the face for money. Sometimes that's the same thing.
Geek the mage first. If you can't find a mage, geek the troll with the assault cannon first.
Proper Planning Prevents Piss Poor Performance
KISS - Keep It Simple, Stupid
Addicts are easy marks. Find their poison of choice, and you've got an instant 'in'. People will let the 'candyman' into the most well defended places if they need a fix bad enough.
Nothing brings a corp reprisal squad down on your head faster than high body counts and massive property damage.
Do not kill needlessly. When you need to, kill without hesitation. There's no 'second place' in a fight to the death.
Don't get pinned down. The other side has a lot more weapons, ammo, and men than you do.
Always expect a trap at the meet. Always. Most times, nothing will happen. When something does happen, being prepared can be the difference between life and death.
If you can't avoid a trap, go in as hard as you possibly can. If you're good (and lucky) you can force your way through before the trap has time to close.
Skillwires are not a substitute for skills.
Use all your available ASSets. Corpsec, wageslaves, and gangsters sometimes need 'companionship', too.
Speak to others with respect. Whether they're a ganger or a corporate exec, respect can go a long way to getting you more nuyen and fewer doublecrosses.
Never assume someone is dead until you've verified the corpse and disposed of it completely, and in several different areas.
