Excalibur 2555 AD is an action-adventure game developed by Tempest Software and published by Telestar Electronic Studios in Europe and Sir-Tech in North America for the PlayStation in 1997 and ported to Windows by Fish (UK) later that year.

Excalibur 2555 AD plays similarly to Pax Corpus, in that players roam through fully 3D environments with a female character in a futuristic setting, and collect items which can be saved for later use.
