I also have EDF 5 now. The discount was timed perfectly, just as I reached my arbitrary goal for 4.1. Which was to complete the game on Normal with all four classes. (I did two of them online and two offline.)
One time in EDF 4.1, I called in a vehicle and a stampede of spiders kept me from reaching it right away. When I did, I found that it was flipped upside-down.
I could still get inside, but of course the wheels just spun ineffectually and I couldn’t go anywhere.
Another time, the king of the dragons repeatedly knocked my vehicle (with me inside) from one side of the map to the other. The view reminded me of SimCity as I flew through the air.
I hope it’s okay that I posted some 4.1 screenshots in the 5 thread. I will presumably have some 5 screenshots in the future.
