Amplitude Studios and Sega are currently having a free weekend event for the Endless series on Steam.
Both Endless Space 2 and Endless Legend will be free to play until Sunday, and both games and their DLC are heavily discounted. Players can also get a free copy of the original Endless Space through Amplitude’s Game2Gether platform.
Both free players and existing owners of Endless Space 2 can also work together this weekend to unlock new content. Amplitude will track the number of systems players discover using exploration probes during the free weekend, which in turn will unlock free content for everyone in the next update.
