I think this new game mode has been vastly underrated and i think I could understand why. If you are a long-time player and have many powerful plants designed for Arena and Penny's Pursuit, then you...
I have finished all 30 levels...i have to say some are tricky. There are 2/3 levels where its level 1 plants being chosen for you and i am just swearing at them zombies. Some really nice zombie ideas, love the theme and actually the zomboss have got to be the most colourful of them all xD
Took me 3 tries at level 17 before I figured out to use plant food to refresh the gold bloom. Easier when you can replace the plants Tweedledum and tweedledee ate.
I try to play this with M1 profile and even using the 1st set of world plant is way over power, this is a good time if EA can reconsider and allow player to create a new level 1 profile to enjoy this new mode to its full potential.
With level 1 profiles it is much more enjoyable, I even learn that Stilt walker zombie can walk over Chard Guard and lost one of my lawn mower in level 3.
There is also a bug in the game on level 4 that the Winter melon attacks the tombstone in the preview screen and you can move it to clear out all the tombstones before starting the game. 👿
