This game is freaking amazing! although, whats with the mystery matches? I would like to know the map and game type before hand so I can choose my class and loadout accordingly. 4/5
This is completely pay to win, all the decent guns are insanely expensive and they only way to actually buy them is if you purchase in game currency with real money. You COULD buy some guns by doing playing the game but 1 coin per kill is ridiculous and if most people dont have that much time on their hands.
Thank for your suggestion. It has been taken note by the developers :)
