All in all, the update is great. Better graphics, new maps, new class. Those are great. But one free class for days on end? Before hand it was about 4-5 which changed hourly. People have preferred classes and may not be able to afford buying others, so I honestly think it's a bad side of the update. It might loose you players, too.
It's an awesome, simple game. Although the companions reviving thing needs to be fixed. Also Survival and Run'n'Gun mode are kind of the same, I feel like they should be a bit more different. Overall, great game that passes time really quickly.
