The fire battlefield is full of vulcanos, lava and sun. This battlefield is good for Ciblles because they have habit and have special uniforms for that! If you won in this battleground (if you are not one of the Ciblles) you will be awarded with some respect points. Remember: "This is one hot battle!"
The water is what we need, but when you fight under it... That isn't good! Nobies are specialists in this terrain. They build some underwater bunkers and have good uniforms with more oxygen. You can be rewarded (if you are not an Nobie) by some respect points if you win in this battlefield!
Icecold... Brrr... Solos are good in this battles because they live in this situations. Battle looks like Nazis vs. Red Army because Red Army know the snow! If you win and you are not an Solo, you will be awarded with some respect points. "Uh... Hope nobody gets in. It's cold that I can't pull trigger!". "No problem! We can always throw icicles on an intruder! Haha!"
Wind is on! Battle begins! Parkaters are prepared for this, so if you win them you will be awarded with respect points from commanders. There are just rocks and dry trees! No sun, no rain, no clouds! "Run and if you die, you will die with reason! Stop, and you will die without any reason!".
