Microsoft's alien-killer gaming thrill, Halo 3, has broken the U.S. sales record for a new video game by garnering an estimated US$170 million in its first 24-hours on sale, the company said late Wednesday.

The performance beat the previous record setter, predecessor Halo 2, which raked in $125 million within 24-hours after its launch.

That's not all. Halo 3 has beaten other records. More than 1.7 million copies of Halo 3 were preordered in the United States, making it the fastest preselling game in U.S. history, Microsoft said. The game also drew more than 1 million Xbox Live members to play online in the first 20 hours on offer, making it the biggest day for Xbox Live gaming in history.

The video-game industry has enjoyed sizzling sales this summer in the United States, according to the industry researcher, NDP Group. In August, video-game software sales rose nearly 23% year over year to $488 million, while overall industry sales totaled $993 million, including consoles and other hardware.

Sales figures for Halo 3 were collected for the United States only, and the figure will likely stand much higher after Microsoft tallies results from overseas. Halo 3 launched in 37 countries at midnight Sept. 25 and is available in 17 languages. It retails for about $60.

The title could go on to become one of the top international sellers of all time, but it faces stiff competition. The top-selling console game of all time, not originally bundled with a console, is Pokémon Red, Blue and Green, at 20.08 million units, according to figures compiled from the Web site Magic Box's Japan Platinum Game Chart and its U.S. Platinum Videogame Chart.
