For those with the Bad Target thing, just kill the drone things until you reach level 6, then move onto th next sector and start killing the Mercenary things there for one of the missions, it's how I did it.
@Mtx 11 That's because Facebook earns him MORE money then Kong does, so no offence, but all of you should shut up and accept it, since until he does update Kong, it stays that way. @arnold1073 I disagree, since sometimes i attack a person to destroy a target building so it stops upgrading as revenge, auto-repair would ruin that factor.
@werker5 Um, wrong, your logic is invalid, WoW is nothing like Minecraft and does not try to copy it, although many games try that as far as I can tell, they always fail, since Minecraft is a unique game and doesn't deserve crap like game copy's.
I got attacked by "frenchkiller" with 1 worm and 72 zombies, then 8 of those weed things, all in one attack, i'm not really sure if someone went ahead and bought tons of zombies, but I can only hope that there are moderators to moniter for hackers.
