Run Slaver Run!

You are the last surviving slave trader after the battle which saw the baRoka archers wipe out your best musketeers. 

Your musket can shoot one paintball at a time. 

Now you have to get on your eager MTB steed and race past the ambush where hidden archers await... 

Free beer if you get one of 'em and reach the end without a rubber arrow up your saddle.
