That you for showing me this unique opportunity @Capt C, however I do believe @INS Mysticis a more avid fan and will be up for playing.
Unfortunately due to exams I don't have time to play... sorry.
Take off all keys, wash them thoroughly in hot soapy water then rinse. Then use a earbud/very fine cloth to clear out gaps in between keys. Did this on Saturday and it's 10x better now.
As far as I am aware the police don't use ESP. Police don't receive map markers on civs, civs receive map markers on cops.
@DI Joseph Tadworthmay know more about this.
