In The '90s, ADK only made games for the Neo Geo arcade machine and console until 2003, when they filed for bankruptcy. After that, SNK bought ADK's properties and inserted them into their universe, starting with the Crisis Crossover Fighting Game NeoGeo Battle Coliseum in 2005, where appearing alongside characters from SNK's own franchises such as The King of Fighters, were characters from World Heroes and Aggressors of Dark Kombat, some of ADK's more famous games from their 90s glory period. And that was just the beginning.
ADK made a variety of games: in The '80s made various sports games and combat flight Simulation Games, some of them licenced by external companies as Sega and SNK (before they went exclusive), but in The '90s ADK expanded more making action-adventure Games and fighting games, with World Heroes series probably their most famous title (and to some their only well known one). After shutting down, ADK lives on, with their characters appearing in SNK games mostly as cameos and releasing compilations of their classic work.
Notably, the Neo Geo was co-developed by ADK with SNK, being an evolution of the Motorola 68k-based architecture used in ADK's late 80s games like Time Soldiers.
