Bonus objectives
There are many different ways to achieve bonus objectives. In almost every level, you can complete a bonus objective by listening in on conversations (for example, in the 1st level, sneak up and hide in the bushes from the 1st 2 sentries), or


there are other ways by gathering intel, capturing Bosses, recon sentries, or blowing something up (for example, in the last level, place C4 on the helicopter).

Make Hq Repeat Themselves
When on a mission, HQ sometimes gives you orders or tells you what the next move is. If you do not hear what she says, say 'I said' in your headset. She will repeat the last thing she told you over the headset.

Third Person Night Vision Goggles During Online Play
Whenever you are in a level that allows you to use night vision goggles (for example, Shadowfalls, Rats Nest, Desert Glory), you can eliminate 1st person night vision goggles. To do this, hold Select and press Up(2), Back, Up. The night vision goggles will now be activated, but the view will be in the normal 3rd person. This makes game play and vision much easier.

Seeding Chaos: Easy sniper rifle
After meeting with the informant Mallard, go to the largest section of ruin just past the building that you met him in. There should be a guard patrolling it and a few boxes of ammunition lying around. Once at this ruin, turn left so that you are facing towards the road that connects to the bridge. There should be a small section of wall, on which a Sr-25 SD is located. Getting this weapon will allow you to kill the guards and the sniper in the watchtower easier, which should prevent the alarm from being raised.

Seeing Without Night Vision Goggles
Adjust the contrast on your screen or your brightness for dark levels on multi-player and single player levels. This will make night vision goggles unnecessary. This works very well on Frostfire and ShadowFalls and can be done in single player mode and online.

Admiral Difficulty Setting
Win the game under the Commander difficulty setting.

Secret Headset Commands
Yell 'Intimidate' into the headset while your crosshairs are on the enemy to make him/her surrender more easily. Your SEAL team will then yell at the enemy to 'Get on your knees!', 'Drop your weapon!', or 'Hands in the air!'.
