Space Engineers launched into Steam Early Access on October 23, 2013, and has been continuously updated and expanded over the years. To celebrate this milestone, the game's developers are giving away a special anniversary gift to all players. Everyone who owns Space Engineers will receive the "Ancient Engineer" character skin in Space Engineers 2. This skin is inspired by the original Space Engineers 1 Engineer suit and allows players to carry a piece of history into the new game. The developers are also releasing a new Steam bundle that combines Space Engineers 1 and Space Engineers 2, allowing players to explore both games and shape the next chapter of the series.

The developers are also working on new content for both games, including a free update for Space Engineers that adds new gameplay mechanics such as guided missiles and heavy torpedoes. This update is part of the Warfare 3 pack, which also includes new blocks and character-combat improvements. Meanwhile, Space Engineers 2 has just received a major update called Hostile Encounters, which brings combat NPCs to the game for the first time. These enemies will bring new challenges to the game and allow players to engineer battlefield solutions and destroy enemy structures.
