There's quite a few fan-generated homages to Bioware's sci-fi universe out on the interwebs but surprisingly few use the twist that "Assignment" does. Featuring two Alliance operatives named Hale and Meer, the clip by Sneaky Zebra Productions lets players choose between alternate endings pegged to Mass Effect's signature good-guy Paragon or kind-of-a-jerk Renegade behavior poles.
"Assignment" isn't as shiny as other amateur homages but its low-budget feel makes one think of a crossover between the rough-and-tumble future of Joss Whedon's Firefly and the sleeker reality posited by Mass Effect's fiction.
