thanks, I read the Lesser guide to Mad Island, do I need to do the Uncensor patch for this version of the game and should I download a dlc ? and one last question what's the point of raping a female native they just keep fighting with me
Remove male MC's pants. If his junk is badly pixellated - you need to uncensor with none.bat. But you probably don't.
DLC is about loli and shota content. Download it if you want to, or just because you want the maddest island experience.
when it comes to Grappling when I press R my char just bend native over and rapes

while Giant natives hiting me with bats
It is impractical to use grapple when there are other enemies around. You need to do it with the last remaining enemy, or lure the target away from the group. Which makes sense - why should they just stand around and wait while you're raping their comrade?
Are you, perhaps, using grapple on knocked-out enemies? In this case, you should know that you can use it on conscious enemies too, male MC will hit their head against the floor or something while you click a lot. Which is how this ability substitutes for a faint weapon such as a club.
