In the world of computer games, it is the denouement to match Harry Potter and the Deathly Hallows: what will happen to Master Chief in his epic battle against the evil alien Covenant?
But as fans queued up last night for the global launch of Halo 3 - the final chapter in the blockbuster series - the game's climax had already leaked out on the web.
Cheats uploaded the movie-like scenes on to YouTube, potentially spoiling the enjoyment of thousands of players.
The Halo games, which play on Xbox, have made hundreds of millions of dollars for its makers, Microsoft. The game went on sale across the US a day before Europe, and in New York about 500 people turned out for the midnight launch. Alex Escobar, who was one of the first in the queue, said: "It is worth it. It is time to finish this fight," echoing the tagline for the futuristic "shooter" game.
