Enriching the original game's experience, Besiege: The Splintered Sea offers a new expansion to the popular physics-based builder. In The Splintered Sea, players battle through a 10-level oceanic campaign, introducing new block types to bring more chaos to the high seas. Using elements of hydrodynamics, this expansion challenges players to explore new builds capable of above-water combat and undersea exploration. Test your creations in the expansion’s new sandbox, which sees players sailing through a vast archipelago, exploring ancient ruins, and putting their engineering to the test on water courses. Using The Splintered Sea’s eight new aquatic blocks, you can spread your destruction across land and sea!

Launched in Ver. 1.0 in 2020, Besiege continues to reign in the builder genre. Using an intuitive building system, players can construct war machines to destroy villages, annihilate armies, and obliterate castles. With over 70 building blocks available, players can achieve success or epic failure through the limitless creativity of their machine designs. Conquer Besiege’s 55 single-player campaign levels, spanning four island nations ripe for conquest. Players can test their builds in an expansive sandbox environment; once you’re ready, enter the Besiege Multiverse, a multiplayer experience that supports head-to-head combat, intricate puzzle solving, and cooperative conquering.
