I have made a quick Review video that mostly talks about the achievements and how easy it is to complete. I have a few problems with the game overall. For example, because it is free it features some 'Mobile-Game' tactics to keep you coming back each day. The build time for shelter upgrades is absurd at times; even taking upwards to 24 hours to complete an upgrade.
Gun play is fine but feels inconstant. Additionally, ADS sway is ridiculous for a lot of guns; so anything with a zoomed optic that you can hold your breath with is preferred.
