for survival. Once you have unlimited ammo just hold it down in the middle and right click. it will keep firing and zapping everything that comes near while you walk away
was on the last duck and it glitches out trying to get into the quarter-finals and came up with climbing training instead. So i refreshed and it let me finish it but now the first duck i did its says hasn't been done -.-
Aw darn, I was thinking of adding that as a game mode, where you're permanently rotating ;)
