Sweet Tooth is a really interesting character I usually play as Kratos and Sly but he is really good as well and very fun to play as
Some things that I've learned while playing as him
There seems to be a way for him to shoot the sawed off shot gun 2 times fast in rapid succession. It happens right after he lands on the floor after a jump if you time it right. I haven't completely figured out how it works and have been more succesful with the downward version but its really cool.
His fire breath can be used for a very short forward movement/momentum. The benefits of doing this over the shoulder check is that can do it multiple times I did it up to four times before
I think his Level 2 missle however should be more controllable I see what its supposed to acheive but it moves way to slow and has to much weight to it unless there is a way to make it more agile and faster that I don't know of.
Also I notice the new Beta players are getting much better at the game and matches are more fun because of that.
