McNeil successfully captured Vega's stronghold and attempted to interrogate Vega, however, Vega's drug-induced insanity and Kane launching a nuclear strike on the facility prevented McNeil from getting anything more than cryptic hints about the origin of the alien warship. Upon rescuing Tratos, Solomon sent McNeil to Central America to assault General Vega's stronghold. He did, however, encounter a Forgotten mutant by the name of Umagon, who promised the support of her Forgotten comrades in return for GDI support in rescuing their leader, Tratos. From the Phoenix base, however, McNeil attempted to and did secure an alien warship Nod's General Vega crash landed, although he was unable to secure any significant hardware.

Although he succeeded in driving Nod from the region, GDI suffered heavy losses. GDI's Commander McNeil was initially deployed to stop a Nod task force attacking GDI's outpost in Phoenix, Arizona. These events marked the beginning of the Second Tiberium War. Immediately after, Kane initiated combat operations on a number of GDI positions and contacted General James Solomon, aboard the GDSS Philadelphia. Slavik, who saw Hassan as a traitor to Kane, overthrew Hassan's leadership, while Kane simultaneously revealed himself to the Brotherhood. GDI, however, mitigated Nod's effectiveness by installing the puppet leader Hassan over the largest splinter faction of Nod. This 'disappearance' made Kane immortal in the eyes of some of the Brotherhood, which allowed Nod forces to continue operating even thirty years later. Despite winning the First Tiberium War with the Ion Cannon strike on the Sarajevo Temple complex, GDI forces were unable to account for the body of Kane a singular fact that the GDI High Council later saw as a costly oversight. Tiberian Sun follows Michael McNeil (GDI) and Anton Slavik (Nod) as they command Global Defense Initiative and Brotherhood of Nod forces during the Second Tiberium War.
