ACK 3D

ACK 3D (later ACKNEX and now 3D GameStudio) was a competitor to the 3D Game Creation System in the amateur first-person shooter space. Similar to Power 3D, it started out as a Wolfenstein 3D engine clone, before later acquiring Doom engine style features, and ultimately true 3D similar to the Quake engine. It was used in a handful of commercial games such as 'H.U.R.L. and Hades2'', as well as two advergames for Mr. Pibb and Taco Bell respectively, as well as in countless amateur productions.
