Big Booty Adventures, while having a ridiculous name and cartoony graphics, is actually a pretty good time, it's also less than five dollars. 

The first minute of the trailer is awful, makes the game look totally shit and they need to rework it badly, but keep watching and suddenly they show you what the game is actually about. 

It has an interesting movement mechanic (Which is where I assume the name comes from) where in order to move faster you perform squats, not real ones just dipping your ass out rhythmically.
There's a bunch of different weapons and modes, there's arena stuff, obstacle courses, places to just fuck around and have fun. I picked it up on a whim the other day and i've enjoyed it so far. 

The default settings for comfort and motion are shit though, make sure you set them correctly first thing you do. 

I don't have a screenshot or webm because I am literally retarded.
