Irrational Games

Background
Irrational Games was founded in 1997 in Boston by Ken Levine and other people from the closed Looking Glass Studios. In 2000, they opened a side studio in Canberra. Take-Two Interactive Software acquired these studios on 9th January 2006, 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). These names were used for Bioshock and its sequel before 2010, when Take-Two decided to return the "Irrational" name back "to respect the studio's legacy". It was announced on February 18, 2014 that the studio would close down.

1st Logo (August 21, 2007)
Logo: We see 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".

FX/SFX: The grammophone animation, the logo-changing smoke effects.

Music/Sounds: The music playing before the logo is shown.

Availability: Seen on BioShock.

2nd Logo (February 9, 2010)
Logo: We see a closeup of a Little Sister stacking some colored blocks. We zoom out, where we see a Big Daddy 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. We then see each individual logo on a grungy background: Digital Extremes, 2K China, 2K Australia, and 2K Marin. The fifth cube, depicting 2K Games, is not shown fullscreen.
