Splinter Cell: Blacklist launched last month in the US. Having been on the market for about a week, the game did fairly well. Total sales were under 300,000, though we don’t have the specifics.
Unfortunately, it would appear that Blacklist did terribly (that may be putting it mildly) on Wii U. According to NeoGAF poster “creamsugar”, who has pretty much always been spot on with NPD data, just 1.6 percent of the title’s sales came from the Wii U version. This would put Blacklist’s Wii U sales under 5,000 – a paltry figure, to be sure.
