Note, that this instruction only works on PC version and consoles too.


Whatever you have bound to fire a weapon will display in the yellow text. If you have not bound any key to fire a weapon, then you simply cannot play Call of Duty and maybe, just maybe you should consider playing Fortnite or Battlefield with yourself instead first ( ͡° ͜ʖ ͡°) (͡ ͡° ͜ つ ͡͡°). I will not make an instruction on how to bind a key to fire a weapon in Call of Duty but I do know, that it's somewhere in the game menu -> options. You'll find it if you search hard enough.

However if it's getting that desperate: Last I heard is that if you reinstall the game, then you should be able to shoot again.

Thanks Infinity Ward for the heads up but I'm pretty sure, that we all know already how to fire a gun in Killing Floor Call of Duty.
