Pvz 3 Ideas
VS MODE
an idea I had would be to add is vs mode: this mode can be played both in casual and competitive formats and even custom formats like double production etc
the map layouts the weather and it being day or night would be chosen randomly but each player can switch the layout once
you can only use the plants and zombie you have unlocked and encountered so far
to balance it out plants can use tier 2 fusions after 1 minute and tier 3's after 2 minutes and the zombie either have their cooldowns and/or cost reduced or they unlock stronger forms in those stages
powerups are disbaled and buffs from you upgrading your town are either disabled or the zombies can get buffs from upgrading their town (for example if the zombie player had a plants produce sun 1% faster that would be switched to zombie produce brains 1% faster.
as I mentioned in my other post about plant and zombie mechanics each player can choose 2-3 abilities to use during that level
each player has 7-8 slots (one is locked for a sun/brain producer)
as a another idea you could do a 2v2 vs mode same rules as above but thee lawn is bigger (Instead of 5x12 it would be 8x14)
TOWN RAIDS
an idea I had is a way for other player to be able to raid your town for rewards like seed packets, coins etc
if you were online and someone wanted to raid your town you could either accept it and battle them or decline it but if you are offline they attack regardless
it would work very similar to pvz 1 versus mode with the exceptional of the map (depending on which area of town you are raiding) which zombies are available to use (only zombies you have encountered) also attacking stronger area gives more rewards but is a lot harder while the zombies start with 50 extra brains the stronger bases may have bonuses like more sun more health even starting the battle with plants already there depending which buffs that player has chosen and smaller or easier bases may have plant nerfs or zombie buffs like plants attack 5% slower
SPLIT MAP LEVELS
in some levels you are required to defend both your front yard and your backyard you can do this by clicing an arrow on your screen to switch from your frontyard to your backyard and vice versa
some times the zombies in the front yard are different than the ones in your backyard so you will need to decide which plants to bring accordingly but on the plus side you will start with 50-100 extra sun
