Shepherd and his entire team versus a team from the Inquisition, made up of Inquisitors and their assocates mostly from the eisenhorn and ravenor books
i have taken all the names from wikis so i don't know all the details for the peopel but assume they are at their latest version, best equipment and experience and abilitys.
each team will fight as a team under command of its leader which is Shepard and Eisenhorn. there are two wildcards for each side whowouldn't normally fight on their side butwill do so for this fight.
the fight will take place at the latest version of the halo bloodgulch map the winner is the last team with people alive
