Finding mushrooms:
 When you are mixing mushrooms in your inventory, you will 
 hear a sound. When you are wandering around the same sound 
 will indicated that a mushroom has appeared. You can also 
 wait for the sound to play again to get another mushroom. 
 Note: Listen for that sound when fighting the last Boss. 
 
 More mushrooms:
 When mushrooms appear, collect them, leave the screen, then 
 return to collect them again. Repeat this until they no longer 
 appear. 
 
 Large med-kit:
 When fighting a Deadite or Hellbilly, turn on your chain saw and 
 slash at them. After a few hits Ash should jam the chainsaw into 
 them and keep it there. Then, use the ax and hit the Deadite while 
 your chain saw is still in them. When they die, they will usually 
 leave behind a Large med-kit. You can also use the other weapons
