This is a nice game, it goes really well with the survival theme. I really liked the sandbox like area where you can chop trees and get item drops. Even the different zombies that behave slightly differently and the two zones are really cool.
Sadly I never found a single phone drop so I couldn’t complete the mission, I would suggest improving the drop chance to at least 2/100 or 5/100 for zombies since there is not a lot to explore story/lore wise, with some more work and a story mode, it would be a really cool game!
