Call of Duty: Modern Warfare 2

Wolverines!: This is a long mission, take it slow and clear the streets and eventually you will end up in the small complex of fast food restaurants. Here, you can get the 10 kills with predator missiles. All you need to do is kill all the enemies and hold out, protecting the VIP. You will be informed of enemies entering from X direction, so switch to the predator missile and fire away.

Exodus: This mission is building to building combat, but you have a Striker. Use the laser designator for the Striker to kill enemies. WATCH OUT FOR THE STRIKER! IT CAN KILL YOU! I cannot tell you how many times I've been run over. Once you cross the bridge, take it very slow. Use the striker to clear the outside of buildings. Move up slowly because there are A LOT of enemies. Once you reach the mansion, clear it from the basement up, slowly watching the corners. Once done, use the laser on the AAs and then head to the last house. There are only two or so enemies at the end of the mission.
