For new releases, we usually offer a limited-time beta, where players can participate in a beta test of an upcoming release giving you access to the upcoming content while giving us valuable information about the state of the build.
For Android devices, the easiest way is to simply go to the Google Play store, head to the Critical Ops app page, and simply scroll to the bottom of the page and opt into the beta program.
If the "Join Beta" button is not available, please make sure you are on a correct Google Play account
Alternatively, you can use this link.
For Apple devices, we have a selection based process, where selected users can participate in testing using the Testflight program.
