[9][10] At PlayStation Experience, Kojima had announced that he had partnered with Guerrilla Games, using the engine for development on Death Stranding.

[11][12] According to executive producer Angie Smets, Decima was originally known simply as "the engine" by Guerrilla employees, as there were initially no plans to publicly offer this technology to game developers outside of the company.

However, the newly forged partnership with Kojima Productions meant that Guerrilla suddenly had to give the engine a name for marketing purposes in late 2016; they chose to symbolize the Dutch-Japanese partnership by naming it after Dejima, a former Japanese island that was home to a major Dutch Empire trading post during the Edo period.

[13][14][15] Guerrilla's most recent title, Horizon Forbidden West, used an updated version of the engine.

[17][18][19][20][21][22] During PlayStation Experience in December 2016, it was revealed that the engine had artificial intelligence, game physics and logic tools, featuring resources for creating entire worlds.
