You can avoid paying upkeep if you quit before the first tick, so... Enjoy your 29 seconds of play time per round (or 59 seconds if you time it correctly later in the round and spawn late). A few players have shown me how to avoid upkeep, and it is not by this way. I'm not certain though that upkeep can be bypassed anymore, as the method I was told was back when Defend the Village was a new playing option.
