But now, West has seemingly come out of retirement to join Epic Games, working on the studio's "game devleopment efforts".
Epic Games has hired Jason West, who co-founded Infinity Ward and Respawn Entertainment with Vince Zampella.
At Infinity Ward, West had a hands-on role through most of the Call of Duty series, including the WWII-themed originals and the first two Modern Warfare games, which helped to redefine modern shooters. Epic Games' Fortnite has more than 200 million players on PC, consoles, and mobile devices, and in 2018, it made $2.4 billion from sales of cosmetics and its battle pass.
Respawn's latest project in the in the Titanfall franchise is the hit battle royale game Apex Legends. Epic Games does not have any officially announced games in development beyond their current work on Fortnite and the Epic Games store.
Making another game that successful could be hard, not least because Fortnite followed and capitalized a trend set by another game.
