Acclaim Studios London

Background
Probe Entertainment (first known as Probe Software from 1984 until 1995) was a British video game developer founded in 1984 by Fergus McGovern (who later founded another video game developer, HotGen Studios). On October 10, 1995, it was acquired by Acclaim Entertainment. In spring 1999, it was brought under the Iguana brand as "Iguana London" for a while, before it was renamed to "Acclaim Studios London" a few months later like other studios that were part of Acclaim. The company was folded into "Acclaim Cheltenham" in 2000.

Probe was responsible for porting Mortal Kombat and Mortal Kombat II for game systems except for SNES (which were done by Sculptured Software) and developing Extreme-G and Extreme-G 2 for Nintendo 64. They were also well known for successful licensed games like Die Hard Trilogy and Alien Trilogy, and for including references to Fergus McGovern's name or likeness in several of their games, such as secret "fergalities" in their Mortal Kombat ports, or the sentence "Is that you, Fergus?" presented to players of Trantor: The Last Stormtrooper upon gaining a low score.

2nd Logo (1991-1995)
Logo: Against a black background, we see a slab of bluish- stone with "probe" carved out of it in a curvy black font. The letter "r" is different than in the first logo. "A" and "DEVELOPMENT" or "PRODUCTION", in white, are shown above and below the logo, respectively (the font used varies depending on the game). Sometimes, the logo shines.

Variants:
 * In its early days, the logo was in a color, had a shiny look, didn't have a border part and had the shines around the word "probe".

1st Logo (1995-August 15, 1996)
Logo: The word "probe" is written in white, with "ENTERTAINMENT" in capital letters below. Around the "o" letter, there is a tilted aura circle-like ring making a reflection on the letter "r".

2nd Logo (1995-July 1998)
Logo: On a black background, 5 circles zoom out and place themselves in the middle of the screen, starting from outer rings. A ring also zooms out, leaving a residue trail as it goes along, and white streaks zoom over the circles to turn them into the word "probe". As the last white streak comes in, a blue one comes in under the text to reveal "ENTERTAINMENT" in blue, and a "TM" symbol wipes in. The logo is the same as the previous one, but without any light.

Variants:
 * On the PSX, the logo moves at such a fast pace that it only covers 1/2 of the music. On the Sega Saturn, it is much slower (as seen in the video).
 * On the PC version of Judge Dredd, the words "A" and "PRODUCTION" appear above and below the logo respectively when the logo forms.
 * There is a still version of the logo.

Logo: On a black background, the Probe logo is now in another custom 3D font. The first and last letter of "probe" spread long ends to the sides. The word "ENTERTAINMENT" is in a stretched bold font below the word "probe". There is also a big arc covering the logo, changing its color to white (with a gradient effect).

Variants:

 * On Extreme-G 2, the "probe" word is created by a running car. Then a UFO draws a rainbow-colored arc while the word "ENTERTAINMENT" wipes in, forming the logo shortly before the UFO flies away.
 * On a beta version of Re-Volt, the UFO flies out of the Acclaim logo, then onto a wooden floor and creates the arc as the Probe logo slams down, the UFO stops, and 2 RC cars in the game push it away.
