To get "Champion" Medal: You got to refresh the game after you upgrade it all to fight with the final boss | "Lagtastic" Medal: just put the best quality, put 3d mode on and indie mode while playing | "Totally Worth it" Medal: Check the Premium content and leave it alone for a while.| GREAT GAME!!! 9999999999999999999999/5
pretty good game, getting all the trophies was not hard but it was challenging. it was entertaining and fun. 5/5 stars
btw i recommend upgrade the fire rate and fire spread and critical damage first if you are going for the 1000 chain trophie
