Ok we went through things. Long story short is that I need to work on it. I pretty much only focused on the stock games and ftag. There are script errors because there are many ftag/stock specific things the mod looks for that dont check for gungame. Or methods were changed that the gametype doesnt use properly. Several are things that were likely never intended but still runs the checks.
Also there is no 'knife only' weapon in this mod. I removed it for an OW2 weapon and cannot add it back. So thats why that doesnt work. Perhaps everyone can think up alternatives with a weapon already in the game and changing how some things work. Maybe instead of a knife at the end you get the starting M9, same stats etc and the knife, but headshots only. Everything else misses. Stuff like that.
But anything I do has to be done in scripts so that will have limitations. There are a lot of settings I cant change. Also it cant be something that will take weeks to do.
