Ok well I downloaded the Immure map that was coverted to mac. Then I installed all the pff's and put the immure.map file in the maps folder. But when I started a multiplayer game the map I was on was boardingaction. Can someone help me fix the problem? Thanks

Is there a way that you can just replace the pistol bullet with the plasma grenade insted of just swaping them?
