Amazon's acquisition of the video game streaming service Twitch is now officially complete, according to a new SEC filing.

First revealed in late August, the deal had Amazon purchase all outstanding shares of Twitch for roughly $970 million in cash. This after reports earlier in the year that Google—through its YouTube subsidiary—would acquire the company for similar amount.

In a message addressed to the Twitch community, CEO Emmett Shear wrote, "We chose Amazon because they believe in our community, they share our values and long-term vision, and they want to help us get there faster. We're keeping most everything the same: our office, our employees, our brand, and most importantly our independence. But with Amazon's support we'll have the resources to bring you an even better Twitch."

The day after the deal was announced, vice president of Amazon Games Michael Frazzini said that "Twitch is absolutely doing a great job and we don't want to change that at all."

Twitch is the largest live-streaming website in the United States by a wide margin, according to a report released this spring, and has expanded into non-gaming ventures, like streaming concerts. That position coincides with Amazon's recent push into the game industry. Earlier this year, it hired designers who worked on Portal and Far Cry, and purchased Killer Instinct developer Double Helix Games.

Bloodborne is coming out exclusively for the PlayStation 4, but many fans of developer From Software's previous games, Dark Souls and Dark Souls 2, were able to play them on PC and Xbox 360 in addition to the PlayStation 3.

According to the game's director Hidetaka Miyazaki, Bloodborne couldn't have come out on previous consoles. "I always wanted to make a game set in the Victorian era, but to make it look good—with all the clothing and the architecture and things—required a console more powerful than the ones that were around. the arrival of the PS4 finally gave us that," Miyazaki said in an interview with PlayStation LifeStyle when asked why the game was a PS4-exclusive. "Bloodborne isn’t a game that could have been cross-generation, it was only possible on PS4."

Of course, that doesn't really explain why it's not coming out on Xbox One or PC, but that probably has more to do with Sony's negotiating skills than technological limitations.

Bloodborne will be released on February 6 in North America and Europe, a day after it's release in Japan.
