ATTACHMENTS:
Weapons attachments return in Call of Duty: Modern Warfare 2 with a few changes. Firstly, new attachments were introduced, such as the Thermal Scope and Heartbeat Sensor. Secondly, some weapon attachments are now unlocked through the use of other attachments, such as getting 20 kills looking through the ACOG Scope to unlock the Thermal Scope or 60 kills looking down the RDS to unlock the Holographic Sight. Lastly, the Grip and Grenade Launcher no longer count as a tier one perk. Enemies throughout the campaign will now carry weapons customized with a variety of attachments. When a player goes to pick up a weapon, it will actually tell them what attachments the gun has, except when the gun is using Bling or does not have any attachments.
