Background: Eidos Video Technologies, founded in 1990, took over Domark, Big Red Games and Simis Group in 1995, merging them into Eidos Interactive. The Domark name was still used for one year after the demise. In 1996, Eidos acquired U.S. Gold along with Core Design.
1st Logo
(1995)
Logo: The
EIDOS word in corporate font is in blue and has light blinks on its surface. Below, we can read
VIDEO COMPRESSION SYSTEMS.
FX/SFX: None.
Music/Sounds: None.
Availability: This is an unique logo, because it features the time when Eidos was yet a video compression company (It developed RPL video format, used massively in its games) and have just begun to spread into gaming business. It was available in
Lords of Midnight.
Scare Factor: None.
2nd Logo
(1996-2001)
Logo: Many purple debris and chips move over the dark background. They come together, then disperse, then combine again into a cloud and form a light-purple EIDOS logo in corporate font, with INTERACTIVE below. Then the logo dissolves into fragments.
FX/SFX: Moving fragments.
Music/Sounds: Massive whooshing of debris and fragments. When the logo is complete, the quiet humming is hear.
Variants: The still version on black BG is seen in several games, like the first
Tomb Raider for PSX. The PC and Saturn versions of said game uses the blue text on white BG.
Availability: Seen on games from late 90's.
Scare Factor: Low.
3rd logo
(1997-2000)
Nickname: "Letter-By-Letter Flashing"
Logo: A bright flash, followed by an E zooming out of the screen, then I, D, O and S coming from the (top) right of the screen. Then INTERACTIVE zooms under the EIDOS, and finally PRESENTS zooms under the logo. Then at the end, a bright light fills the entire screen, leaving it white. Then it fades to black.
Variant(s):
- There is a different logo on various games. The animation at the first 10 (or under) seconds is the same, but there is no PRESENTS under the logo, and the blue background is darker. There is no bright flash at the end, instead, the logo shrivels to dust, then it fades into PRESENTS on a space background, and a Core Design logo proceeds. This is seen for all the Tomb Raider games (except the first one), Fighting Force 1 & 2, and other Core Design games for the PlayStation and PC.
- Sometimes, the background is white and the logo is clean blue and still.
FX/SFX: The bright flash, the moving letters E-I-D-O-S, the INTERACTIVE/PRESENTS zooming under the logo, the bright flash at the end.
Music/Sounds: Loud whooshing sounds for each letter flying, accompanied by a crumbling background noise.
Availability: Seen on Tomb Raider games starting with Tomb Raider 2, on Final Fantasy VII (PC Version), Thief and Thief II, among other games.
Scare Factor: Minimal.
4th Logo
(2002?-2003)

Logo: On a cloudy background with the sun in faraway, the light silver letters E-I-D-O-S slide one by one into the view, collecting together into a word, which rotates. The letters of INTERACTIVE appear below for left side to right. The logo hangs tilted a bit, but keeps slowly rotating.
FX/SFX: I think all the animation in the logo.
Music/Sounds: Whooshing letters and rotation noise.
Availability: Seen on Praetorians and Swingerz Golf. It can be also seen on Tomb Raider: The Angel of Darkness.
Scare Factor: None, it's a great logo.
5th Logo
(2003)

Logo: We see many purple lights, moving and crossing the screen. An Eidos logo zoom in from the center, where the intensity of lights is maximal. Then the background becomes still purple.
FX/SFX/Cheesy Factor: The lights. Compared to other logos, this one is poor.
Music/Sounds: Electric-like sounds and two calm whooshes.
Availability: Used in Deus Ex: Invisible War.
Scare Factor: Low.
6th Logo
(2004-2005)

Logo: From a white water surface, the letters of EIDOS, made of crystal, emerge one by one. The crystal point flies from the left and stops to the right of the word. Then the logo becomes purple.
FX/SFX: The logo .
Music/Sounds: Water sounds, then a sound of flowing point, one little "pim!" and a male annoucer says: EIDOS!
Sometimes there is no announcer.
Availability: Used in Thief: Deadly Shadows, Hitman Contracts and Project Snowblind.
Scare Factor: Low, but you can be startled by a sudden announcer.
7th Logo
(2005)

Logo: We see a zooming (possible throught the sniper rifle). There is a vague spot on the screen, and the zooming regulator moves to get a clear view of this figure. We see it is an EIDOS logo. Then the screen turns out.
FX/SFX: The whole action, I think.
Music/Sounds: Static digital noises.
Availability: Seen on Conflict: Global Terror.
Scare Factor: Medium, due to the loud and noisy soundtrack.
8th Logo
(2005 - )

Logo: Against a white background, many blue or purple chips move and zoom out to combine into the Eidos logo made in 3D. The logo hangs for a few seconds, then quickly zoom in and we fly through O letter.

Music/Sounds: TBA.
Availability: Rather Common. Seen on newer games by Eidos like Just Cause or Shellshock 2.
Scare Factor: Minimal.
Final Note: In 2005 the company was bought by SCi, which later adopted the name of Eidos. In 2009, Square Enix purchased Eidos and announced to cease it down to 2010, moving the publishing activities into the name of Square Enix Europe.
