1 - download this addon: https://steamhost.cn/steamcommunity_com/sharedfiles/filedetails/?id=2594153036
It will disable lua_run that disables noclip technically it should disable strip weapons triggers but it doesnt work.
2 - Download OTG admin gun to delete strip weapons triggers.(no link srry lol)
3 - go into map and write in console sv_cheats 1 then mat_fullbright to remove darkness(also place fog editor to remove "darkness" fog.) then write showtriggers 1 and showtriggers_toggle to see triggers. Noclip from lobby to spawn room, while doing this you will probably spot a huge trigger. Heres OTG admin gun come in, that thing is so op that with "universal kill" it can delete even parts of the map like triggers and etc(it wouldnt do anything about brushes btw). press reload key then select "universal kill" and shot it at huge trigger. Done! you completely broke the maps anti cheat and who purpose by giving youself ability to do basically anything, with otg admin gun you can even delete the ghost lol
