Challenge Mode

Modern Warfare 2 online has many challenges that players need to complete. After completion, some will reward weapon accessories, some will reward weapon camouflage, some will reward new signatures (refer to the paragraph on task signature), and all challenges will be rewarded with EXP. Some challenges are one-off, such as destroying two enemies with one bullet, and some are graded, such as using M4A 1 kill 10, 50, 150 and above. Every time you reach a number, you complete a challenge. The completed challenges cannot be challenged again, but all challenges are cleared after rebirth.
