Call of Duty: Modern Warfare 2/Sniper Fi

Wave 1

 * 15 Hostiles

Start off by looking behind you and getting the claymores and the M240 with heartbeat sensor. Plant one claymore near the ladder to the roof of the building you start on and place another at the top of the stairs. Lie on the ground to the right of two boxes and start sniping the enemy, the first wave is the hardest. Occasionally check your heartbeat sensor to see where the remaining enemies are, pay careful attention to see if they are behind you. If they are, get the machine-gun and kill them then continue sniping until the end of the wave.

Option 1: Grab the AK-47 with grenade launcher near the start location. There are two nearby. The second one can be used to replenish the grenades. Arm yourself with a second weapon of your choice.

Wave 2

 * 20 Hostiles
 * 1 Jeep

A predator control unit will appear on top of the two boxes, pick it up, go prone and use it straight away. Make sure you are out of the line of fire, because the missile will go out of control if you get hit. You get an unlimited number of these missiles but after using one, you may not launch another for a set period of time. Aim for the Jeep with the missile then continue sniping the enemies until you get another predator and use that to finish off the remaining enemies.

Option 1: Do not destroy the jeep with the predator missile. Wait for the jeep to come closer to the tanker truck near the heli-pad, then destroy it with the AK-47 grenade launcher from the roof of the start location. The reason to do this is to block the truck in the third wave. Keep the destruction of tanker truckers to a minimum until the last level if possible. The exploding tanker trucks can kill lots of foot mobiles, and you want to use them to inflict maximum damage.

Wave 3

 * 23 Hostiles
 * 1 Troop Transport

Continue sniping and using the predator on vehicles first. The faster you launch the missile, the more kills you usually get.

Option 1: Do not destroy the truck (troop transport) with the predator. Allow the truck to advance near the heli-pad where it should be blocked by the destroyed jeep from Wave Two. Destroy the truck with the grenade launcher from the roof of the start location. Just before all of the hostiles are eliminated, replenish your claymores, and grenade launcher, and run to the heli-pad quickly after the last hostile has died.

Wave 4

 * 24 Hostiles
 * 1 Jeep

Continue using the Predator Missile and Sniping.

Option 1: Deploy claymores near the heli-pad stairs, then use the predator missile to destroy the tanker truck closest to the truck you destroyed in Wave Three. The goal is to move the damaged truck with predator explosions to block the stairs to the heli-pad (it may take more then one predator to move the truck to block the stairs). If you can succeed in doing this, no foot mobiles will be able to enter the heli-pad to attack you. This will give you a degree of safety, but you must watch for incoming grenades. You are most vulnerable when using the laptop to call in a missile, as you will not have time to close the laptop then dodge a grenade. Use the AK-47 grenade launcher to kill the foot mobiles. Use the predator just after a grenade thrown at you as exploded. You will be safe for a short time.

Final Wave

 * 30 Hostiles
 * 1 Jeep
 * 1 Troop Transport

Try to hit the Jeep and the truck with the same missile for a lot fewer enemies to deal with. If this fails then destroy the truck first. As there are more enemies, be careful about behind you.

Option 1: Immediately use the predator missile to destroy the incoming jeep (not the truck). Assuming you have blocked the heli-pad stairs with a damaged truck, you must keep it from being moved by the jeep and unblocking the stairs, thus allowing enemy foot mobiles to attack you on the heli-pad.
