Assault on Tei Tenga

Assault on Tei Tenga, also known as Tei Tenga, is a hub-based mapset for ZDoom created by Sam Ketner. It is widely considered as the first WAD to use the ZDoom hub system inherited from Hexen, combined with ACS scripted cutscenes, that was not a proof of concept. Due to this, it is listed as one of the Top 100 WADs of All Time by Doomworld. Released in May 21, 1999, it originally received mixed responses, with a few warning that Tei Tenga's use of ACS scripts may set a bad precedent of heavily scripted WADs instead of the original Doom experience. Nevertheless, Tei Tenga has been described as "the wad that got ZDoom on its feet".
