Hints:

Big ant in Arizona level:
     Destroy  the  observatory  in  Arizona  and  wait  until the loud
explosion. Examine the big crater in the middle of the level to find a
big  asteroid.  Destroy  the  asteroid and a giant ant will emerge and
shoot everyone in the level.

Fire all ammo:
     Enable  the "Rapid Fire" code, then begin game play. Get any gun,
get  close  to an opponent, then rapidly tap Fire. The gun should fire
all of its ammunition in about five seconds.

Launch Site weapons:
     Go  to the tower in the middle of the Launch Site level. Approach
to the tunnel that does not go through and wait until the lights above
are  green  beforine  driving in. You will be taken up on to the tower
and a booster rocket will be placed on back of your vehicle. Then, you
will  be  shot  into  the  air  and dropped. Collect the weapons, that
include  specials  and  radar jammers. This may be repeated as much as
needed, unless the tower is destroyed.

Triple salvage points:
     Destroy  your  opponents  with  a  special  weapon  to get triple
salvage points.

Flying:
     Collect a Hover power-up, then hold Up and rapidly tap X.

Play your own music:
     Press  Start  during  game  play,  open  the PlayStation lid, and
replace  the  game  disc with an audio CD. When game play resumes, the
music  from  the  CD will begin playing. A prompt for the game CD will
appear after the level ends.

Rolling donut in Arizona level:
     Destroy  the donut shop in the Arizona level without damaging the
"Super  Donut" on top. The donut will roll around the level destroying
enemies. This may be done on each of the two donut shops in the level.

Ghosts in Louisiana level:
     Destroy  the graves in the cemetery. Ghosts will appear and begin
attacking.

Flood Louisiana level:
     Approach  the  bridge  (or dam) and shoot at the nearby wheel. It
will  start  to spin and the bridge will begin to raise. Keep shooting
until  the  bridge  is  completely  raised.  Repeat  this at the other
bridge. In a few seconds, it will start to flood.

Utah Ski Resort level:
     There  are  three  different  snow  games to play. If you do them
properly, you will get extra power-ups, weapons, etc. Go to the top of
the hill via ski lifts, or by just driving. The first game is a skiing
type  slalom  (obtain  the ski powerup first). Successfully slalom the
blue/red  flags.  A  winner's  stand with power-ups will appear at the
bottom,  by  the resort. The second is a ski slope/ramp. To get to the
ramp,  you  must  first  drive  into the tower at the top of the hill.
Drive  down  the ramp as fast as possible. Once in the air, you can do
tricks  and  get  points for power-ups at the winner's stand. The last
ski  game is the luge, all the way on the left. Run the luge (with the
ski  powerup)  and  hit all the check points. Finish at the bottom and
pick  up  power-ups  at the winners stand. All these mini-games can be
done  as  often  as  needed, but you must break your previous score in
order to keep getting power-ups.

Vigilante 8 levels:
     Pause  the  game  &  insert  the  original  Vigilante 8 disc. The
message  'V8  levels  enabled'  should be displayed. Insert the Second
Offense  disc  again,  quit  the  current  game  to  have the original
Vigilante 8 levels.

Attraction mines:
     You  need  at  least  2  mines for this. When you have the mines,
press  left,  right, then down and machine gun at the same time to get
an attraction mine

Hoover tires BOOST:
     When  you  have  the  hoover tires, tap X,X, hold X on the second
time you push it...

Cheats Enabled:
     Play  a  1  player mode survivel game using Dallas 13. Put on all
MOLO  drivers  (the  bus).  Pick  the  Minnesota Level. Now to get the
Cheats  Enabled  secret you have to kill at least 10 buses and stay in
the game for at least 15 minutes. If you do it correctly, you will see
"Cheats  Enabled" underneath the stats screen (that says how many cars
you killed, your time, etc.)
