Ok, this is a guide to help you with getting the secrets in the game. As you know there are 4 secrets in the game. I'm showing you how to unlock them.
Reach for the Sky= with a railgun (or other longrange) go to the crash landing map and shoot to the sky over and over again until you get the medal. Reward= moon corpses mode.
I Hate Natural= With a assault rifle, go to the facility/lab map and go to the place where there is plants hanging overhead on the ceiling. Reward= unlimited ammo mode.
Love is blind= Do the first level on the Human Campain. Before the missile comes down go back to the place where you started and walk into the giant heart to get the medal. Reward= 4x health mode.
Oh Hi Kitty= Go to the frostbite map and go to the big iceberg at the very top.(It is nearly impossible to get there.) Once you are up there, go to the middle and jump. (The map drains your health so be quick!) Reward= lol cats mode.
To activate the modes, when you play quickmatch, select "special mode" to whatever you want. However for most modes, they subtract cr. The best mode is unlimited ammo mode. Thanks for reading!
if you want to get the dance with the heart its simple all you have to do is step 1 go to first level in campaign step 2 go down the thing then jump to the other side then run to the side you were before and then go up then youll see a dancing heart and thats where it is
go to the edge under the iceburg and jump and then move left(i got it from doing it on the left side)and then use the double jump and move towards the top of it and you get on it!!!!!( i find it simple
