Aliens: Colonial Marines has been patched on Xbox 360, PS3

UPDATE #2: A second patch for console versions of Aliens: Colonial Marines has been deployed, in addition to the update listed below.

Amongst a multitude of bugfixes and tweaks, the glitch that showed Xenos displaying "erratic animations" (jazz hands) is now gone.

There's now an increased light radius for player's shoulder lamp (a common complaint) and tweaked enemy and friendly AI to be "more aggressive and responsive" (presumably so you can't just run straight past them now).

The full list of fixes is now available over on Gearbox's blog.
