Casali brothers

Brothers Dario and Milo Casali are best known for creating The Plutonia Experiment, one of two stand-alone megawads for the second official Doom II expansion, Final Doom. The eldest brother, Stefano Casali, is best known for producing the well-known comic strip Love Is.... They are the children of cartoonist Kim Casali.

Avid Doom mappers from the earliest days of creating WADs (a progenitor of the modding and level design practiced today), Dario and Milo began to develop what would become a passion for them in the creation of several independent maps. Although somewhat roughly executed compared to their later work, several of these levels (especially the TheBest series) enjoyed notoriety on Doom forums and listserves for being remarkably difficult. These early levels enabled the Casalis to gain the foundation for what would later become their careers.

Shortly after working on the Memento Mori megaWAD and the Requiem megaWAD which Dario contributed to, the Casalis met several members of the then-popular TeamTNT, a large online group of mappers, and joined the team. These megaWADs were collections of single Doom levels created by WADers and linked together to form an overarching storyline. Dario and Milo enjoyed the collaborative efforts involved in teamwork and having only developed single maps earlier, they could appreciate the magnitude of the finished megaWAD product.

At the time the Casalis joined TeamTNT, a major project was just starting to develop: a ground-breaking 32-level megaWAD to be released for free online. TeamTNT was enjoying a great deal of attention within the Doom community due to their announcement of this megaWAD, and as a result several skilled mappers within the community were eager to join. This flurry of activity attracted the attention of Doom developers id Software, and they began making quiet negotiations with TeamTNT to purchase the finished product for sale as an add-on for Doom. Id also requested that a second 32-level megaWAD be created in addition and for this request, on the recommendation of an employee of theirs, American McGee, they turned to the Casalis. With TeamTNT, the Casali brothers designed several levels for TNT: Evilution (a megaWAD constituent of Final Doom) as well as all 32 levels of The Plutonia Experiment megaWAD independently. During his time with TeamTNT, Dario went under the member name "Number 6", although his usual callsign is "Punisher". Milo has variously used the callsigns "doom warrior" and "Venom". Neither brother has continued work with TeamTNT since Final Doom.
