Intel Laptops
There are 45 intel laptops to be discovered in "MW2." They are available only in first-player mode, and unlike the intel laptops in the first "Modern Warfare," discovering them only unlocks two achievements or trophies. The first laptop is in "S.S.D.D." and it is located across from the obstacle entrance under the watchtower. The last laptop is in "Endgame," and it is located right at the beginning of the mission before you get in your vehicle.
Multiplayer Mode
In multiplayer mode, there are many items to be unlocked. Most have to do with the number of kills one earns. The UAV, which shows your enemies on a mini-map, will be unlocked after only three kills. The highest number of kills is 25. A Tactical Nuke will be unlocked if you manage to kill 25 enemies in a row without dying. The Tactical Nuke is an extremely powerful weapon that kills everyone on the map. Also in multiplayer mode, if a gamer reaches level 70 and enters "Prestige Mode," they will be able to unlock a sixth custom class shot.
Single-player and Special Ops Mode
Most of the items that can be unlocked in single-player mode have to deal with a certain number of kills, the way an enemy is killed or completing different missions in more-difficult play modes such as Hardened or Veteran. Gamers can also earn stars during certain missions in Special Ops mode. If you beat the game, you will unlock the "Museum" level. In this level, a gamer will find crates of ammo and weapons, and they will see a "Don't Press" sign on a desk next to a red bell. Ring the bell and enemies will start appearing in waves. You will need to finish off two waves of enemies to beat this level.
