'''Music/Sounds:''' There are three known soundtracks to this logo:
* A flashing sound, followed by a long synthesised ambient chord and five whoosh sounds. On Eidos/Core Design games, this tune is extended to transition into the Core Design logo. This is the main variant.
* A synthesised bass chord, followed by five whoosh sounds and finally a crumbling sound. Used mostly on the "PRESENTS"-less variant.
* A strange droning sound. This has only been spotted on ''Swagman'', ''Deathtrap Dungeon'', and ''F1 World Grand Prix: Season 1999'' so far (the former using the prototype logo).
'''Availability:''' Common.
* Seen on ''Tomb Raider'' games starting with ''Tomb Raider II'' (the first game, along with ''Fighting Force'', to use the regular version of the logo), on ''Final Fantasy VII'' (PC version), ''Fear Effect'', ''Thief'' and ''Thief II'', among other games. By 2000, it was only seen on Core Design games until 2002.
* The prototype variant appears on ''Swagman'', ''Conquest Earth: First Encounter'' and other early PC titles.
* One of the last games to use this logo was ''Thunderhawk: Operation Phoenix'' (aka ''Thunderstrike: Operation Phoenix'' in North America and Japan).
