GUYS If you are having trouble at beetle shield then try this. First fight a beetle if you get a wild berry then your chances of getting a shell is higher if anything else then it stays the same. just farm beetles in first second and third areas. KEEP THIS POST ALIVE!!!
There should be defense modes and attack modes and stuff like that so that your turrets can focus on specific enemies and I forgot boss/big enemies mode.
LOLZ shot a tank with a flamethrower in front of me and then he was LITERALLY flying off to the other side of the battlefield LOLZ. like this comment if you think this is a glitch
