- Crest — Germany, founded July 1988
Crest was founded in July 1988 by Crossbow and Goldrush, and would become one of the most technically formidable groups in the German demoscene — Crossbow alone holds a 9.8/10 coding rating on CSDb across three decades of output. The intro's centerpiece is a pair of oversized CREST logos built entirely from hardware sprites, deliberately symmetrical and dominating the screen — a knowing echo of the sprite-logo tradition established by #2 Eagle Soft Inc. three years earlier. The SID is Drax's Kuldioxid, composed in 1989 during his Vibrants period, eventually appearing in over a hundred scene releases. The intro was attached to 6 cracks including Turrican +17 and Black Tiger +11H.
