I googled and got the process which is

Part 1
1 press "`"
2 type and enter "sv_cheats 1"
3 type and enter "restart"

part 2
when the game is restarted press "`" and enter the required cheat "god" or "noclip" etc.

i did it but its not working. i did part 1 successfully and game restarted now when i m entering cheat it is ineffective

as i m entering

"`" "weapon_ak47" "enter" "Ecs"

what is that i m doing wrong?

please help thanks
