alr guys here are some tips if you are playing ultrakill (from me) IN CYBERGRIND

If a stalker spawns alone IMMEDITLY KILL IT
If idols spawn destroy it first then kill the enemies
if a hideous mass spawns use hammer swapping which is the same as shotgun swapping but better if your experinced
Then If their are maurices and Guttermen Flip coins and shoot one and boom
