So the cheat or console command that people have the most trouble with is impulse 101 ill get into the other console commands later but for now lets get the hard one out of the way ive had alot of trouble with impulse 101 i found this if you type sv_cheats 1 then restart and then impulse 101 it works just fine since people say you gotta restart the map to get impulse 101 to work

ok so now the other commands there are 2 ways of getting these commands to work for god and noclip you can quick save and quick load or you can do what you did with impulse 101 sv_cheats 1 and then god or noclip tne restart

This works with every hl1 game or hl1 mod enjoy your commands i recommend you put impulse 101 god and noclip to a bind for ease of access
