Retail has noted a surge of interest in free-roaming action game Crackdown, since the announcement that the game disc will include a beta key to the multiplayer testing of Bungie's highly-anticipated shooter Halo 3.
Specialist chain GAME says that pre-orders for Crackdown have risen by 25 per cent since Microsoft unveiled the initiative.
"Halo 3 is one of the most highly anticipated Xbox 360 titles for 2007 and our customers are hungry to get hold of it," commented, MD of GAME Group's online business.
"Halo 3 beta is a great way for gamers to actually influence the making of the game and will ensure the production of a truly amazing game," he added.
Crackdown, from developer Realtime Worlds, is due for release February 23 in Europe. Copies of the game which include the Halo 3 beta key will be housed in specially marked packaging.
