Strategy

4X strategy

Strategy games built on four actions: explore, expand, exploit and exterminate, played over long stretches against rivals.

Also called: 4x, 4x game, explore expand exploit exterminate, empire builder, kingdom builder

What defines it

  • A base or empire that you build up over weeks.
  • Armies, heroes and resource gathering.
  • Alliances with other players, with shared goals and rivalries.
  • Timers for building and research, and events that run for set periods.

The four X words describe the classic shape of the type: look around the map, claim territory, put it to work, and defeat rivals. Mobile versions add alliances and real-time clocks.

Many mobile 4X games are closer to base-building strategy than the original desktop 4X games. The name is used loosely.
