If you haven't gotten these achievements, it is must likely you've been suffering like me, whenever i tried to get them it was fully impossible because: 1) Arrow simply disappeared in thin air and did not hit the target - 2) It simply just went throw the Watermelon/Zombie.

After a lot of research i couldn't find a simple solution for this and i thought i would never achieve the 100% achievements goal, but after playing around with other games, i came across a simple and yet obvious solution, here's a quick guide to fix the Bow/Arrow problem and get this achievements:

1) Go to Library, click on NMRIH.
2) On the top Right (As of 06/5/2024 U.I Overlay), click on settings and go to the options ''Properties''.
3) Click on the Betas Tab.
4) On the top Right you will see a scroll-tab that says ''None'' for the Game versions, click on it and select ''Previous - Previous versions of the game''.
*5) An older version of No more Room in Hell will start to download, wait until it is finished, open the game and you can get the achievements!.


It seems this error is in the new versions of the game, meaning you can easily get it in older versions, i hope this could help my fellow NMRIH players.
