Good, but needs update.

I get that the fourth game in this series has been released, but many people (including myself) prefer the more arcade style this game has, so get back to the updates. The biggest issue I have with the game is that you can unlock everything in the game (guns, armor pieces, ranks, and buffs) with an in-game purchase. That really takes the fun out of a game. Also, there needs to be a greater variety in the challenges. I know that there is some variety, but most of them are very similar. The only challenge that stood out was the Blocked doors. In this challenge, you have better barricades, but must constantly go around fixing them or be overcome by a massive horde of zombies. Pretty creative! There should be a challenge where you must go from point A to point B for a rescue pickup, and have a time limit as well. I am aware that it would require new maps, but they can be exclusive ti the challenge, or be part of one of the continents that hasnt been added yet. This leads into my final point: the game feels unfinished content wise. There are multiple continents that havent been added, but are labeled "Coming Soon!". It has been over a year since the last update, and those continents still are not added.
