Touhou Gouyoku Ibun Sunken Fossil World Switch ... Apr 2026

The sprawling, bullet-hell soaked universe of Touhou Project is expanding its console footprint. Following the success of previous spin-off fighters on the Switch, publisher Phoenixx and developer Twilight Frontier (known for the Touhou Hyouibana and Koumajou Remilia series) have officially launched Touhou Gouyoku Ibun: Sunken Fossil World (also known as Touhou: Sunken Fossil World ) on the Nintendo Switch.

This release brings the unique "puzzle-action" hybrid gameplay of the PC original to a handheld audience, complete with exclusive features and all previous DLC characters. Released initially on PC via Steam in 2021, Sunken Fossil World is a competitive two-on-two fighting game with a twist. Unlike traditional fighters that rely on long combo strings or motion inputs, this title focuses on vertical danmaku (bullet hell) patterns and a unique "Burial" system .

On 1 May 2014 a paper published in Phys. Rev. Lett by J. Khuyagbaatar and others states the superheavy element with atomic number Z = 117 (ununseptium) was produced as an evaporation residue in the 48Ca and 249Bk fusion reaction at the gas-filled recoil separator TASCA at GSI Darmstadt, Germany. The radioactive decay of evaporation residues and their α-decay products was studied using a detection setup that allows measurement of decays of single atomic nuclei with very short half-lives. Two decay chains comprising seven α-decays and a spontaneous fission each were identified and assigned to the isotope 294Uus (element 117) and its decay products.
