Guerilla Games' PlayStation 3 exclusive shooter Killzone 2 is, by Sony's own estimate, already a sales success. With some 500,000 copies already solid in the U.S., Sony says it's breaking internal records.

Sony Computer Entertainment America's vice president of marketing Scott Steinberg tells GameDaily that Killzone 2 "set the record as the most pre-ordered SCEA PS3 title to-date." On top of that, Steinberg says, the game is also "the fastest SCEA PS3 title to break the 500,000 unit mark and it's also the highest selling SCEA PS3 title for the first 30 days out of launch."


Yes, the game may not have sold as spectacularly as some of the more emotionally invested would have liked during the first month of tracked sales—323,000 copies in February, which actually only accounted for two days worth of sales—but it appears to be holding steady in its second month.

We'll have a better idea how it held up in March, when the NPD Group releases its sales figures next week. Until then, don't worry about sales too much.
