Personally I was quite pleased by both the trailer (albeit it having a ripped Video Co-Pilot introduction) and the full MEHEM end cutscene. Nevertheless the mod is basking in positive fanfare from a majority of Mass Effect players, even knowing the mod is still quite in its infancy.
At the moment the mod is a work in progress, but promises to deliver much more qualitive versions of MEHEM. MEHEM was created with one purpose in mind and that was to fabricate an ending that effectively remedies many of the controversial issues still present even after Bioware presented their very own 'ending cutscene patch,' also known as the Extended Cut which was downloadable for players of Mass Effect 3. Enter MEHEM, Mass Effect Happy Ending Mod, a modification created by DSOGaming for Mass Effect 3 designed to give an ending that 'Shepard deserves,' made by a diehard fan for diehard fans.
Seldom does one see a gamer passionate enough a game to willingly and meticulously change the ending course of a game to fit their desires.
