Unicorn Chomper Question

If you have, or acquire, Garden Warfare 1 and then grind your way through it until you hit Rank 313 you will be able to use the mailbox in Garden Warfare 2 to check your GW1 rank, at which point the game will award you with a special sticker pack containing the Unicorn Chomper and his special Rainbow Warp ability.

If you start from scratch in GW1 and play the game towards doing the Star Quests which are required for ranking up and you spend your Skip Challenge Stars on the stuff which requires huge amounts of luck or which is just down right crazy time consuming you can hit Rank 313 in about 225 hours as a minimum. Make no mistake; it's a grind and you'll probably come to hate the game since hitting those challenges means that you have to play a certain way sometimes with certain characters and you'll need to play all of the character classes up to their maximum rank of 40.

Bear in mind you need to do this before February of 2017, which gives you about 6 months. After February they have stated that the character/rank importing feature will be ended.

I stream every monday on Xbox One to unlock my unicorn chomper, Im quickly hitting half way there (gaining now 3-4 ranks a day about 10-12 a week with only a couple hours of play). One thing I can suggest is dont bother spending coins on anything but the 10k frozen sticker pack. They give me now after a lot purchases/ranks of only buying that 2-5 skip stars per pack, every now and then i get a 10x skip star pack. I am now in a sweet zone where I can complete, 4-5 challenges a character per G&G and skip the other 10. I earn back more than I spend each time i play and now have 250 skip stars and 400k of coins to buy more packs. 

When you first start purchasing the pack you'll end up with a lot character decorative pieces but eventually (usually around rank 35-50 if you only spend your earnings on that you will get mostly skip stars). play garden ops to complete plants challenges quickly and easy, saving your skip stars for the stupid challenges. (you'll learn the stupid ones quickly).
