They also released a spinoff, XCOM: Chimera Squad, last year.
Not content to just release a good sequel, Firaxis stepped up to the plate and hit another home run with the massive War of the Chosen expansion, which has been regarded as, essentially, XCOM 2.5. XCOM 2, upon its initial release, was met with high praise and was regarded as a step up from its predecessor, a successful reboot of a long-dormant franchise.
