okay... so, wave 39 on sd blitz. not too difficult right? well, i was deployed as the gunner covering the front 2 doors. (for almost the whole game....) BOOM. kicked for idling apparently. i dont know if this was a server problem or if its a problem with the design of the game but it was quite frustrating. dont worry though. i came back and we got to wave 71. NEW PERSONAL RECORD!
It appears the same mechanic used to kick players on crossfire is used on Blitz too. On Crossfire, its 90 seconds of not moving.
