Galactic Strike Force does not have individual player turns. Instead, there are five stages each round, and all players may act simultaneously or in any order they choose during those phases. The five phases that make up the gameplay of Galactic Strike Force are:
Travel – Players may move their ship to another sector.
Requisition – Players may purchase cards from the Station in their sector
Installation – Players may install Techs from their hand to their ship.
Battle Strike – Force ships engage in battle with Opposition ships in their sector.
Aftermath – The round clean-up phase.
Many cards have an icon which references a specific phase. Upon beginning any phase, first check for any such icons in play. Those actions happen immediately upon beginning that phase, in whatever order the players choose.
