ISDC offers an immersive science-fiction starship simulator centered on the Starship Endeavour. Participants can explore new worlds, encounter new civilisations, and take part in missions involving tactical, scientific, exploratory, and diplomatic challenges. The experience also invites users to form a crew, with an online academy designed to help members prepare for their missions.

The simulator features a detailed fictional spacecraft, described as 148 metres long with seven decks, powered by a magneto-inertial fusion reactor generating 4GW. Its systems include Graticule MIE engines for in-system manoeuvring, a Graticule faster-than-light drive for interstellar travel, sensors for exploration and defence, and guided-missile torpedoes.

ISDC provides information about several crew roles, including tactical, science, and engineer officers. Tactical officers monitor the ship’s environment and support its defence; science officers analyse discoveries and advise on responses; and engineers maintain ship systems, repair damage, and manage power. The site also shares news and updates about the Endeavour’s design and the simulator.
