All the way through Evil, the game is building up to the doomsday devise. And at the end you have a twelve minuet wait while the rocket is assembled (you are under siege at this point). When the rocket is constructed a big red button appears on the screen ready for you to finally launch the doomsday devise, but even after this buildup (which starts the moment you start playing) you are rewarded with only a ten seconds of FMV sequence. And not even a good one at that.
I was expecting something done to music, but the ending just feels empty and to be honest I wouldn't have minded being given to opportunity to continue playing afterwards.
