Not to bad so far. Game is free and doesn't require you to buy to have fun. Worth downloading. It is just like every other apocalypse type survival game though. So don't expect it to be different and you won't be disappointed. Have fun. Had a 4 star review but now I give it 2 stars. Update came along and ruined everything. Most time I can't even log in. Guess it's time to delete game and find new one.
