The launch of Assassin's Creed Unity seems to be causing some trouble for developer Ubisoft. The BBC reports the company's stock price has dropped by nearly 13 percent since Unity's release on Tuesday, and the company has created a Live Update blog dedicated to keeping its customers abreast of what the developers are doing to fix the game. In effect, Ubisoft is pulling back the curtain a bit to keep the public abreast of its development process; the most recent blog entry reassures customers that the company is developing an update to address widespread graphical issues (seen above, pardon the soundtrack) as well as specific glitches that cause protagonist Arno to do things like fall through the ground or get stuck inside world geometry. The troubled launch of Unity is especially interesting to game developers in light of the company's previous complaints about the game's production costs. Creative director Alex Amancio previously noted that adding a new stealth option to Unity was surprisingly complex, while women protagonists weren't added at all because it was "a lot of extra production work."
