The latest Twisted Metal was a fun game, and very few people will argue against that, but it was missing some of the spark that made past Twisted Metal games memorable. My biggest pet peeve was that there were only three endings, one for each of the story characters, and there was no way to unlock more. However, the original game design didn't intend for it to be that way, and some new videos show what could have been.
David Jaffe has just posted two new videos on his YouTube account and they include additional endings that Eat Sleep Play wanted to integrate into Twisted Metal. As mentioned in a couple of developer interviews before release, Twisted Metal (2012) was supposed to have three endings for each of the three story characters (that's nine endings for you Math wizards) which would be based on the difficulty you beat the respective story character's campaign on. What ended up happening was the launch deadline came sooner than expected and Eat Sleep Play was forced to consolidate the vision into just one ending per character.
The first video is the original ending for Dollface which was going to be unlocked by those who beat the third story tier on Normal difficulty. Check it out:
Another video shows the other two endings for Dollface as well as more Preacher footage which would be unlocked with them. See below:
I believe the biggest mistake that Eat Sleep Play made was choosing to use live action with actors and then interface the footage with heavy editing. As you could probably tell from the videos that did make it into the game, each of the cut-scenes had high-production quality, and as a result required a lot of time investment. If they instead chose to use basic cutscenes like seen in past games there's no doubt in my mind that they could have fit a lot more into the game. It's difficult to blame them for wanting to try something new, especially now that we're in 2012 and just about every developer is trying to be revolutionary, but hopefully they return to the original style in the next release.
