Once you get enough upgrades the cannonball goes from "eh" to "destroyer of worlds" which is pretty nice. Between that and the scatter ball you'll be wiping everything out in less than a second. Best bet seems to be to keep cannon balls, scatter balls, sniper balls, and plasma balls about even, do about 10 or so poison balls, and don't use the basic ball at all.
Why didn't you tell us about the monster in the forest? Would have been nice to know before literally crapping my pants. Also, where is the secret zone?
During the motorcycle ride, I ran out of ammo. I failed, and tried to go to safehouse to restock on ammo. Because going to safehouse triggers the mission, I started out with no ammo. Just retrying doesn't leave me with enough ammo. Not to mention the fact that headshots don't work. Seriously, the game is unbeatable at this point.
Superfun, but a little slowdown near the end of my run. Also sign here if you think this game needs badges,darkness8450, salamander23, LaTale, JohnnyLira, cole1114
