Guild Wars Campaigns: Offline Play? No—Online Only

No. Guild Wars (all campaigns—Prophecies, Factions, Nightfall, Eye of the North) is an online-only MMORPG. Every aspect requires a live connection to ArenaNet's servers:

• World instances, quests, and missions are server-hosted.
• No offline mode or local save exists.
• Character data, inventory, and progress are stored server-side.

What You Can Do Offline

• Create characters (but cannot save/enter world without connection).
• Use the Offline Training Arena (skill practice only—no XP, loot, or story progress).

A stable broadband connection is mandatory to play any Guild Wars campaign.
