Modern Warfare 2 (2022) PC: Internet Required

Yes. Call of Duty: Modern Warfare II (2022) on PC requires a persistent internet connection for all modes—including Campaign.

Why Online-Only?

• Campaign: Streamed assets, cinematic loading, co-op support (post-launch), battle pass progression tracking, telemetry.
• Multiplayer / Warzone 2.0 / DMZ: Dedicated servers, matchmaking, anti-cheat (Ricochet kernel driver), live service economy.
• Anti-Cheat: Ricochet runs at kernel level; requires constant server heartbeat.
• Licensing/DRM: Battle.net / Steam online verification at launch.

What "Offline" Looks Like

• You can appear "Offline" to friends (social status).
• You cannot launch the game without Battle.net/Steam online handshake.
• No LAN mode. No local bot matches.

Minimum Connection

• Stable 5+ Mbps down / 1+ Mbps up.
• Low latency (<80ms to regional server).
• NAT Type Open / Moderate (Strict breaks matchmaking/voice).

If your internet is unreliable or metered, this game will be frustrating. Consider MW2 Campaign Remastered (2020, standalone, offline) or older CoDs (BO2, MW3 2011) with LAN/bot support.
