If you're going to fight fuse in Fuse No More,
I strongly recommend you don't actually complete it. (I think it's not worth it. Here's why...)
What I mean is, if you finish it, you get the purple fuse breaker hurricane gun
thing (sorry haven't played FF for a while)
BUT you will no longer be able to go inside Fuse's Throne,
fight Fuse again (for lolz or for rare items)
or to fight those small Don Dooms. (Also for lolz or more likely, rare items.)
All you have to do is to NOT talk to Samurai Jack in Fuse's Throne before fighting Fuse.
That way, you can do the mission again (yeah, you'll never want to complete but it's worth having access
to the throne in my opinion) and you can grind or explore there again. (Without the purple fuse breaker but
in my opinion...big deal!
There are better looking guns of the same specs anyway.)
Of course it's up to you if you want to finish the mission and get the purple gun
and never be able to play the mission again. (Unless you make another character, starting
all the way from level 1 to 36.
Just helpful advice, which I wish I knew about when I had the mission....
Stupid purple fuse breaker....
