A1: Gameplay:

You start out at the entrance of the casino. It's the night before it's Grand
Opening, so guards are posted everywhere. The first thing you're going to need
to know is that you run out of ammo real fast in this game if you're not too
careful. Every level has an unlimited supply of ammunition hidden somewhere,
so your number one goal in each level is to locate said ammo drops. To cut
back on constant backtracking to reload your gun(s), try to always nail
headshots. The enemies aren't very smart, and usually give you plenty of
opportunity to kill them with one shot. Body shots can almost empty and entire
clip before killing an enemy. So remember, headshots are key to enjoying this
game.

Your first ammo drop is behind the desk to your right. Head there to get 15
extra bullets. If you don't like how slowly your character turns, you can
always adjust the Aim Speed in the Options menu. Once your loaded up, get
ready for action. There's a lot of guards on this floor of the casino, so use
your brains when encountering enemies, and take full advantage of your
surroundings. Taking cover is essential to progressing in this game. So I'm
not gonna hold your hand through the gunfights. Simply take cover, popping out
for headshots until you reach the next yellow dot on your map. Crouching
during gunfights is also a good idea. Don't try to rush through, patience and
cunning are the only way you're gonna beat this game. If you're able to get
close enough to an enemy without getting shot up, you can always use your
knife for an easy one-hit kill.

When you reach the next yellow dot, you'll notice a med pack hanging on the
wall. DO NOT TOUCH IT! Only grab it if you need it, as it heals on contact,
thus using it up entirely. It's always a good idea to leave med kits along til
you need them. When you reach the 2nd yellow dot, you'll be at the end of this
section. I suggest fully restocking your ammo and health before proceeding,
although you can always return back to this section if neccessary.

The next section of the casino, you may notice some guards running around in
the distance, preparing to find cover. So do the same and take em out. These
guards may seem a bit more aggressive than before, so don't stand around
waiting to get shot. Take the offensive and clear the path. When they're dead,
another wave will appear near the steps. Find a good vantage point, and pop em
all in the head. Work your way to two yellow dots, an ammo pickup and a med
pack. Use both as needed, but be careful, as two more guards will start
shooting at you from the balcony.

You'll need a security card to gain access to the next area, so head upstairs
for now, turning left and down the path til you hear a door opening, then
quickly crouch to take cover. You can still be hit from this angle, so it may
be easier to run all the way to the other side of the balcony and take cover
behind the boxes there. The guard with the security card you need packs a mean
shotgun along with extra armor covering his body, so a headshot is crucial on
him. After he's dead, pick up the card and his shotgun. Now you're in
business. Go back downstairs and enter the double doors by the ammo pickup to
clear your first mission objective.

Now to find the vault. You'll notice a dramatic change in music along with a
guard standing behind a glass window with his back turned to you. You couldn't
ask for a better headshot. Another guard may rush you if he hears the other
guy die, so stay on your toes and take him out. There's a med pack in the room
the first guard was in, so if you need it, take it, although there's more than
enough med packs in this section to keep you breathing. After that, you have
the choice to go either left of right. The right path is where the locked
vault is located, so head left for now.

Kill the guard behind the glass window, preferrably without entering the room.
If you get too far into the room, two more guards will show up from a well
hidden path in the hallway, leaving you little room for cover. One of these
guards has the Security Level B card, so kill him and take it. You can enter
the room the two guards came from for another med pack, otherwise use the card
to proceed through the door next to the guard you just killed. There's a lone
guard walking a set path along the hallway, and if you're careful enough, he's
an easy set-up for a stealth kill with your knife. The next door you come
across will have an ammo pickup, use it then go to the last door. There are
three guards huddled together in here, seemingly having a conversation. Use
your momentum of surprise to take them out. In other words, pull out your
shotgun and run in balls out, blasting away. They'll never know what hit em.
There's a med pack and the Security Level C card in this room. Turn around and
head for the vault.

Take out the lone guard guarding the vault. Now look for markings on the vault
door, and press X when prompted to plant the C4 and blow the lock. There's a
room full of pissed off guards in the vault, so don't quit yet, you're almost
to the diamonds, the third and final objective (or so it seems). When you've
secured the diamonds, it's time to make your escape. Turn around to see four
more guards taking up posts outside the vault. Pull out your shotgun and
slaughter them, before heading back towards the casino's entrance.

/Avoid the cops

Okay, this is where most people get frustrated and subsequently quit playing.
The game has stealth levels, but does a piss-poor job of implementing them.
The good news is there are only three of them in the entire game, and with my
guidance, you will get through every one of them with absolutely no trouble.
These levels are the reason I even opted to write a FAQ to begin with, because
I had trouble with them and there was no FAQ available for this game to help
me out. So I painstakingly devoted myself to mastering these damnable levels
in hopes that others will use my strategies and continue playing this game,
instead of quitting like I wanted to do on several damn occasions.

Alright, so you have four cops investigating the casino, and you can't kill
them or let them know you're there, as that would reflect badly on the
Coladangelo Family. So you're going to have to get out of the casino
completely unseen. First off, turn left and up the stairs, preferrably taking
the right path, but it really doesn't matter. Run towards the boxes if you
took the right path. Now comes the annoying part. Waiting. Crouch and wait for
two cops to come up the steps. They will each investigate both paths, but you
won't be seen if you're by the boxes, or if you're at an equal distance down
the other path. When they start going back downstairs, wait for the 2nd cop to
start heading down before quickly making your way downstairs too. Now just as
quickly hide the game tables on your left, preferrably the one furthest from
the stairs, til one of the cops starts making his way towards the steps again.
This is key, you absolutely have to position your body so no part of it is
visible to the passing cop. It doesn't take much to get the officer's
attention. Now wait til he's completely past you before making a break for it,
hugging the left wall as much as possible, all the way to the casino's
entrance. JOB COMPLETE!
