After creating the article, I figured it would be a good idea to make a blog post about it, too.
Here are some choice quotes from producer Randy Varnell:
"If you don't curse the design team at least five times on the way to beating this guy, we haven't done our jobs."
"You can fight Terramorphous multiple times and he's going to drop different loot every time. Some of the best gear in the game, great legendary items, will drop from this guy. He has specific items that only drop from him in the game. There are some legendaries you'll only find from him."
"A lot of the end-game pull is that four-player co-op challenge at a high level against a really tough-to-fight boss. He is designed to be impossible. I'm not going to say he's not soloable, because I know how well gamers break games, but he really is tuned for that end-game, four-player co-op fight, testing your build and your gear and your equipment and your ability to work together as a team. His rewards are great. So, if you are that end-game player, this is your challenge right here."
I wonder how long it will take for the YouTube video to appear that shows Terramorphous being soloed. :)
