Battlefield 4 (BF4) builds upon the foundations laid down in Battlefield 3 (BF3) improving the game in all of its elements
with immense destruction, vehicular combat, gunfire and added polish with the Frostbite 3 engine.
Plus, in Appalachia, coal is now mined by using explosives to blow the entire tops off of mountains, which causes
immense environmental
destruction, filling and polluting streams and ravines
with rubble and toxic minerals.
