Found the following in this [url=]http://www.the-spoiler.com/STRATEGY/Simon..schuster/mob.rule.1.html[/url] FAQ. Hopefully thats what your after.

3 Attacks

You can attack the enemy in multiple ways, and we'll discuss each
one.


3.1 ATTACK FACTORIES

Instead of burning the factory to the ground, it's usually easier
to send over 4 fixers to convert it (along with a few gangsters
as escorts), then sell the converted factory. You gain the money
also. Just make sure the enemy doesn't do the same to you.


3.2 CONVERT THEIR BUSINESSES

Convert their businesses, start on the edges and work your way
inside. Send in a group of fixers (like 4) and you can convert
the whole place in like 10-12 seconds.

Try to convert the businesses making babies first, as that'll
hurt them more. If you keep doing it, they'll run out of units.

Once you've taken over the business, sell it back to the city and
it'll be torn down. If you keep it, you will have to send over a
tenant and maybe a fixer to help keep it up.

You should be CONSTANTLY converting rival businesses to shrink
the enemy turf in size and get money at the same time.


3.3 ATTACK TENANTS DIRECTLY

Attack the tenants may seem a bit low, but unoccupied buildings
will eventually grow roaches. After that, the building will
slowly grow worse and go BOOM. Remember, you're not fighting a
war, you're fighting fellow gangs.

To accelerate building decay, dump the dead body(ies) back into
the now empty building.


3.4 TAKE OUT WORKERS, FIXERS, AND SO ON

Fixers are usually pretty fast so it's hard to kill one unless
you corner one inside their property. However, workers move much
slower and are easier to kill.

Gangsters are harder, but if you have 4 gangsters together and
maybe a couple fixers tagging along, the gangster will go down in
no time. Weapon upgrades always help.

What's better... stuff the dead bodies into their properties.
That will accelerate building decay (then roaches and so on).


3.5 GHOST ATTACK

Attack with ghosts can accelerate building decay, causing the
resident to leave, or at least pay no rent and don't reproduce.
If you ghost their "money block" their pocketbook will take a big
hit.
