When buying upgrades for your gun, always look at your gun information beforehand. For example, if your gun has a gunpower of 10.8 and you see that the upgrade reads lvl 2 --> 10.5, you are basically losing out and wasting money....From: donald_spyder26
This trick really only works up until you get to the castle where the enemies get stronger. The easiest way to save ammunition is to use your knife frequently.

You will get the command ...From: AC girl

Zealots are the hooded Ganados in the castle area. They are tough, and take more punishment than your average Ganado. Watch out if the parasite in them pops out of their heads.

Here I found a trick that we can avoid the plagas. For the villagers shoot their head with handgun and then use"kick", this will avoid the plagas. When you in the castle and Island kill the castellers and Islanders by using "suplex", this will avoid their plagas. Sometimes the plagas will come from their head, when the plagas co...From: solomon
