I found five hidden hearts (Grandma's, forest, lab, mountain, indie house). How many are there, and what is there purpose? I haven't done the game a second time and can't figure out what to do with the secret area.
Wow. This is a fantastic game. I'm only halfway done, but I did the winter games, and my, the difficulty curve is perfect. Music is fantastic, gameplay is the same as the original, with added features. This is a perfect sequel. 5/5
Step 1: Get bow.
Step 2: Crossbow.
Step 3: Remington.
Step 4: Scar (as secondary).
Step 5: Win. Easy game, barricades took no damage, and I used no explosives. After getting the remington, it was only on day 40 did a melee guy get a kill (I missed a shot :P) 4/5
