When you kill another player with a headshot, a metal "ping" sound will play to confirm it.

Killing all three RPG enemies in the pursuing trucks in Game Over results in SSgt. Griggs saying "Success!"

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.

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.

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.

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.
