The makers of DomiNations are launching a big update that enables players to enter the “atomic age” in the Civilization-like mobile strategy game.

The new content is aimed at making the mobile game seem fresh for its existing players. DomiNations has been downloaded more than 28 million times since Big Huge Games launched it in the spring of 2015. It launched a major World War update in December 2015, and then Tokyo-based Nexon acquired Big Huge Games earlier this year.

Big Huge Games and Nexon M say the update is the biggest content renewal yet for DomiNations, which enables players to lead one of eight unique nations from the Stone Age to the Space Age. To date, DomiNations has grossed more than $62 million, according to measurement firm Sensor Tower.

Following the World War era content from earlier updates, the Atomic Age includes a series of new units and buildings that represent the decade following the end of World War II. To represent the era’s technological progress, Atomic Age introduces new Wonders of the World and two new game changing units: the Helicopter and the Armored Personnel Carrier (APC).

The Atomic Age allows players to build an additional Wonder of the World from a new list, including landmarks like the United Nations, The Pentagon, The Atomium, and Sydney Opera House. Each provides powerful unique bonuses. For instance, the United Nations spawns a peacekeeping force of all the unique units from all nations and provides bonus National Trade Goods each day.

The Atomic Age also introduces powerful new attack options with the Helicopter and APC. The Helicopter is a flying siege unit that fires from a distance that is outside of the range of most defensive buildings, but is weak to fire from defending troops. The APC is a sturdy ground vehicle that deploys additional heavy infantry every few seconds and lays down covering fire with its machine gun. Both are very powerful when carefully protected and used strategically.

DomiNations is available as a free-to-play game on the iTunes App Store for iPhone and iPad and on Google Play for Android devices.
