It took roughly two years and "one of the most expensive art assets ever" to get Cyberpunk 2077: Phantom Liberty's Chimera tank fight right

Cyberpunk 2077: Phantom Liberty's Chimera tank boss fight required roughly two years of development, according to CD Projekt Red. During an episode of AnsweRED, game director Gabe Amatangelo and creative director Igor Sarzyński discussed the intricate sequence that incorporated gameplay, narrative, art, and worldbuilding. Art director Paweł Mielniczuk and Amatangelo exchanged emails about various military equipment, ultimately selecting heavy artillery to instill fear in players.

The team iterated on the fight multiple times, with Mielniczuk noting they "were doing the tank I think four times, changing equipment, the weapons." The Chimera tank fight, described by Sarzyński as "one of the most expensive art assets ever," proved to be a worthwhile investment, standing out as an exciting moment in a DLC expansion filled with such moments.
