2K Boston

Background
On January 9, 2006, Take-Two Interactive Software acquired Irrational Games and its Australian side studio, and a year after, the "Irrational" name was dropped and the studios were incorporated into the 2K Games label, renaming them 2K Boston and 2K Australia respectively (in 2007, 2K Marin was also spun off by five people from 2K Boston). The 2K Boston name was only used for Bioshock in 2007, while 2K Australia operated until 2015. In 2010, Take-Two decided to return the "Irrational" name back for the Boston studio "to respect the studio's legacy".

1st Logo (August 21, 2007-October 21, 2008)
Visuals: There is an art-deco grammophone playing old-style music. When the camera comes close to the recording disc, the 2K initials can be seen on it. Then the 2K sign flashes into the 2K Boston logo, which looks like the normal 2K Games logo, but it's and the word "BOSTON" replaces "GAMES". Then, the town name is wiped out by smoky effects and replaced with "AUSTRALIA".

Technique: CGI by EyeballNYC.

Audio: The music playing before the logo is shown.

Availability: Seen on BioShock.

2nd Logo (February 9, 2010)
Visuals: There is a closeup of a Little Sister stacking some colored blocks. The logo zooms out, where a Big Daddy is seen behind the window. It stomps the ground, causing the cubes to fall and revealing that each block has a different one of the games' companies on it. Each individual logo then appears on a grungy background: Digital Extremes, 2K China, 2K Australia, and 2K Marin. The fifth cube, depicting 2K Games, is not shown fullscreen.

Technique: A mix of CGI and 2D animation.

Audio: Some ominous game-world sounds.

Availability: Appears on BioShock 2.
