SuperPower 2: Steam Edition

SuperPower 2: Steam Edition is a real-time geopolitical simulation in which you control a country across political, economic and military affairs. Develop your country, expand its influence and compete against sophisticated AI or other players. You can use sanctions, alliances and military action, manage treaties, and make tactical decisions during conflicts in a 3D environment.

Countries and conflict

All 193 real countries are playable and use data drawn from the CIA World Factbook, the United Nations and U.S. military databases. The AI simulates each country and takes diplomatic relations into account when deciding whether to annex regions under its military control. Battles model real-life combat situations, with forces joining and leaving as the balance of power shifts. Modular unit building lets you assemble forces in real time.

Politics and diplomacy

You can create or break treaties, form political alliances and impose economic sanctions. Embargo treaties reduce relations. Peaceful annexation depends on population support in both nations; a shared religion or language is also required, and the nations involved need at least one in common.

Military campaigns

For a sea invasion, you need capital ships within 750 km of the region you are trying to invade. Enemy fleets must be more than 1,500 km from your invasion fleet. The combat radius has been enlarged to make frontlines easier to establish, and allies make more measured decisions during wars: they will not help if you can handle the conflict yourself.

Game modes

Play solo scenarios or use sandbox mode. Multiplayer supports up to 32 players across several styles, including world domination and economic master.
