Dead Space 3's chart-topping debut in February amounts to 605,000 copies, the NPD told GameSpot, proving that February was a relatively slow month for video games in the US overall.

Launch sales for the first Dead Space in the US came in at around 500,000. EA said Dead Space 2 approximately doubled that launch performance two years later – but regions were not specified for that, so it's hard to compare US performance.

In any case, at 605K, that puts Dead Space 3 ahead of 1, and still part of a series of games that just don't seem to be massive hits at launch. A rumor from earlier this month, which EA denied, suggested that a proposed sequel was no longer in development.
