Save The Earth Moves To Paid Version In About One Week
The permanent-free-copy window is the whole story: anyone who claims the game on Steam now keeps it after the paid version and its update land, which makes the next seven days the decision point for the existing free build.
Reporting from 1 source: Game Spark.
GameFirst announced that the environmental conservation sim Save the Earth will transition to a paid version in about one week, tied to a large update that adds a visual overhaul, a rebuilt scenario selection screen, an integrated music player, and new scenarios. Players who add the free Steam version to their library before the change, and those who claim a free license from now on, keep it permanently. New paid players get three Initiative Packs and two free packs daily.
The free build is playable on PC via Steam. The paid version brings a visual overhaul, a rebuilt scenario selection screen, an integrated music player, and new scenarios, and it grants new players three Initiative Packs plus two free packs each day.
GameFirst's claim terms are permanent, not a grace period: adding the free version to a Steam library, or taking a free license before the switch, keeps the game playable after the paid version goes live. The announcement was published on October 6, with the change scheduled about one week out, so the window on the free version closes on that schedule.
