Cheat options
Collect the Intel Pieces (enemy laptop computers) hidden throughout the game to unlock the cheat options. The number of pieces you have determines which specific cheats are available.
| Unlockable: | How to Unlock: |
| A Bad Year | 15 Intel Pieces. Enemies explode into tires when shot. |
| Cluster Bombs | 10 Intel Pieces. When a frag grenade explodes, four more will explode in a cross-shaped pattern. |
| CoD Noir | 2 Intel Pieces. Allows black and white graphics. |
| Infinite Ammo | 30 Intel Pieces. Reloads are no longer necessary. This has no effect with single-shot weapons such as RPGs, C4, or Claymores. |
| Photo-Negative | 4 Intel Pieces. Inverts the colors. |
| Ragtime Warfare | 8 Intel Pieces. Silent movie mode. |
| Slow-Mo Ability | 20 Intel Pieces. The game slows to half speed when you melee. |
| Super Contrast | 6 Intel Pieces. Increases the contrast. |
Sniping
If a target is moving make sure to lead it. If you are not making shots try to lead your target more. Also, if you are a skilled sniper try using the M40A3 over the M21. It has a slower reload time and rate of fire, but it has enough damage to kill a target in one shot instead of two or three. It also allows you to be less noticeable with less rounds being fired; so someone else cannot follow the tracer shot back to you. A good setup for the sniper is the Claymore perk, to alert you when an enemy is trying to close in on your rear, and either the Sleight Of Hand or Stopping Power, then Iron Lungs to give you more time to line up your shots.
Game Over: SSgt. Griggs's "Success!" comment
Killing all three RPG enemies in the pursuing trucks in Game Over results in SSgt. Griggs saying "Success!"
Multi-player: Headshots
When you kill another player with a headshot, a metal "ping" sound will play to confirm it.
Golden Weapons

| Unlockable: | How to Unlock: |
| Golden Ak-47 | Complete all Assault Rifle challenges. |
| Golden Desert Eagle | Get to Lv.55. |
| Golden Dragonuv | Complete all Sniper challenges. |
| Golden M1014 | Complete all Shotgun challenges. |

Crew Expendable: Desert Eagle
In the second large containment room, run ahead of your team. There are two enemies with Desert Eagles who will try to surprise you around two corners, depending on the path you take.
Better accuracy
Once you get the Red Dot Scope addon to your weapons, use it over the ACOG scope. The red dot will not enhance or take away anything and provides a better aimpoint on most weapons. The ACOG scope will actually add more range to your weapon, but take away accuracy which accomplishes almost nothing; especially so for snipers because it takes away range and adds nothing.
Intel Pieces
The Intel Pieces can be found in the following levels. There are a total of thirty Intel Pieces.
Level 2: 2 Intel Pieces
Level 4: 2 Intel Pieces
Level 5: 3 Intel Pieces
Level 6: 2 Intel Pieces
Level 7: 2 Intel Pieces
Level 9: 3 Intel Pieces
Level 10: 2 Intel Pieces
Level 12: 2 Intel Pieces
Level 13: 3 Intel Pieces
Level 14: 2 Intel Pieces

Faster experience
To level up quicker than usual, try to use the same gun until all the marksman and elite challenges are completed. They provide huge boosts and will quickly level you up to get new guns. However, do not use those guns yet. Just keep on the challenge until it has completed. The third phase of the challenge usually ends with 1,000 experience points and that will bump you up a rank almost in itself. Also, do not forget about the strange challenges like jumping 15 feet and surviving or falling 30 feet to your death. To get that one if not previously unlocked play the "Countdown" map and jump into one of the open missile silos. You will get instant experience points for simply dying. Also, remember to go prone and crouch to get those challenges as well.
