Awesome game + some suggestions on future updates

-every 25lvls for our survivors guns should change Thier appearance looking at it as improved , also changing its shooting Sound
-every promotion we do for our survivors should change thier appearance, like adding more gear around them making them look cool
-multi-player or coop would work?hmm would be interesting but who knows if it will happen
-more gore/blood?
-Also when we do missions and pick an item like for example the vest , it should show its appearance when you choose an item
-add an item that makes everything go slow motion for a certain amount of time?should help throughout certain situations like the BEAR which really annoys me lol
Well that's all also keep making this game great and I'm looking forward to the updates that will come

Thanks for the suggestions.
