Unreal Engine

Background
Unreal Engine is a game engine developed by Epic Games, originally created for the 1998 PC first-person shooter game, Unreal. It has since become a popular tool used by many game developers today. The animated logo was first presented for the release of Unreal Engine 3.

1st Logo (2005-2011)
Logo: We start on a very complicated red rectangular space, where several transparent details join and create the box with Unreal logo inside. The name is written on the lower section of the box, with "TECHNOLOGY" below that and "POWERED BY" appears above the box. Golden sparks emerge from the box and run over the background, then return back.

Variant: A still logo exists. They use either a black or white background.

Technique: Animation of the shield and the logo.

Music/Sounds: A technical composition of whooshing and electronic clanks, with two notable hissing sounds when the electronic sparks leave the box and return.

Availability: Common. First used on a demo presentation of RoboHordes, later renamed RoboBlitz, and was seen on a lot of games.

2nd Logo (2010- )
Logo: We start on a black, when the giant bright U letter comes and zooms into the concentrical red circles, which zoom out and beyond. The letter is joined by the usual white circle, which turns red. The words appear to be the same, but without the box. When it finishes, the logo shows some noise and vanishes.

Variants:
 * On Kinect Adventures, the logo was stitched on fabric.
 * On Mighty no. 9, it is still.

Technique: The logo forming, made in perfect animation.

Music/Sounds: A single technical whoosh.

Availability: Current. Seen on Bulletstorm and following titles.
