Wall-Nut Hills Mansion
I'm glad that we still get one map to play with on G&G but having to play this map over and over made me realize that the mansion in Wall-Nut Hills is practically impossible to defend. The idea of it is fine. Usually the strategy seems to be to set up as many obstacles and traps in front of the door as possible to prevent them from entering. Only it seems like as long as a zombie makes it within a 4 ft.(ish) radius of the door, it counts as an entry.
I can't count the amount of times I vanquished a zombie at least a few feet away from the door where the game counted him as an entry. It's hard enough to guard against the scientists that will warp to the door, it's even harder when all somone has to do is hop over a row of tallnuts, KO on a potato mine a few feet from the door and still count towards their goal.
It's great if your playing as the zombies but terrible when playing as the plants.
I could also be wrong thinking that an entry counted when someone entered the upstairs door. Either way, this final stage is far too easy. It is over before it reaches the 2:00 mark if even that.
