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!
to get the lol kitty, it is actually very easy you just need to get near the spines platform (right or left, both are the same) at the top so you will see that when you jump you will be helped by the shape of the platform which is like a hill near the spines, but no so close to them, then jump moving to left or right (it dependes) in which platform you are, and just before you start falling you double jump again and there you are in the iceberg, i did it at my first try and basically I can always do it
For I Hate Nature, I suggest the Shredder. Then Go to facility Map on Quick match. check to see if there are little leafs are falling down. if it doesn't then you don't have a chance
Uhm, what does the 'Moon Corpses' mode do? I tried to find out like 3hrs, and i didn't, plz help
It makes the corpses (dead bodies) float around, kind of like low gravity. This is only good if you are trying to get the 'Corplosion' skill bonus. Other than that, it's useless and it gets in the way when sniping.
