Black Cheats (PlayStation 2)

Silver Weapons ... Clear the game on a difficulty and the weapons will be silver with
unlimited ammo on that difficulty or less, excluding 

BlackOps

Black Ops Difficulty ... Clear all stages on hard difficulty.

After you melee once, press the reload button, as soon as you do that, press melee again.
You will have performed two melees with less than a second delay between them. You can
continue this cycle for as many quick melees as you wish.

In the final mission in the last standoff room, there's a door in between the twin bunkers
that will not open. On the left of that door is a lamp. If you stand beside the lamp, you
should be covered fairly well by the wall the lamp is hanging from. The guards cannot get
to you nor may they shoot you; however, you can shoot back at them.

Use 5SQQ-STHA-ZFFV-7XEV a profile name (new profile). Note there must be a dash between
each set of alphanumerics. Once you confirm the profile name, the game will ask for a
second (real) profile name. This code lets you have an MSAW in place of your side arm.

You can't prime grenades in Black, and enemies will often run away from grenades the
moment they see them. To make your grenades explode instantly, shoot 'em with your guns.
You don't even have to be totally accurate.

You can only carry two weapons at a time, but you can relocate a third weapon to a
strategic location or next part of a mission. 

For example; just prior to negotiating a "fence" point (map feature such as broken stairs,
or a ledge) where you will no longer be able to back-track a map to aquire a weapon. Since
the game doesn't give you a checkpoint at these mission locations, it's a very final
moment in the game, because there's no going back once you drop down. 

So here's one way to make that moment much more fun. Note that when you exchange, or
pickup a weapon there is a small delay in the weapon exchange. During that brief time you
can walk forward quickly and relocate the dropped weapon to where you are now standing. In
theory, you "could" drag a third weapon with you through an entire mission . 

The fastest way to learn and use this trick is to step back from the third weapon you want
to drag with you, hold the "pickup weapon" button down, and then walk over the third
weapon while continuing forward in the direction you want to go. The weapon you drop
during the exchange will be relocated to a new location (just like the change weapon trick
in Halo one). 

Where this really comes in handy is when negotiating a fence point in the game. You can
actually drag a rocket launcher or other weapon (or multiple weapons for that matter)
right up the the edge of the "fence" point, and drop them over into the new area of the
mission.

When you need to reload, hit the reload button and quickly press the melee attack button
to cancel the reload. Immediately press the reload button again to reload your weapon
without the obstructive distance blur.

Play the coloured game and pay attention to your reticule. When it shifts colour from
white to another colour, you are targeting something interesting: 

Red is hostile target. 

Blue is a destructable secondary objective. 

Black is destructable environment. 

Green is a friendly (rare).
