MEHEM, the Mass Effect Happy Ending Mod just got updated to v0.5. The biggest change is that the mod now uses the DLC method, meaning it is self contained in it's own DLC, rather than changing game files that already existed. This increases compatibility with other mods and general user convenience.
Other updates include the addition of Miranda and Jack to the memorial scene (if romanced by Shepard), a higher quality final flyby video, fixed subtitles and a restored NG+ import capability.
With switch to DLC also gives us more freedom for further additions in future versions of the mod, so stay tuned.
