Mass Effect and Assassin's Creed Crossovers
Templar Effect by donamatter reviews
The result of the Templars dominating Earth, politically, commercially and militarily. The replication of First Civilisation artefacts by Abstergo Industries saw the first ship on Mars in the later quarter of the 21st century where they discovered the Prothean archive. The first contact between Turian and human panned out far different with the Templars in control. Protect and win.

Joker's Let's Play Series by Sutori-Artifex reviews
Join Jeff "Joker" Moreau, pilot of the Normandy SR-2 as he explores some of humanity's most ancient video games... for 2185, that is. (Note: Largely a Crackfic, as characters do not act as they usually do, but I'd consider it "canon" to my Masscreed universe. Rated T for Violence, Horror, and Language. Subject to Change based on "gameplay".)
