One of the most atmospheric zombie games. Fantastic sound design and gritty environments. Especially when players encounter the Tower of London and Baconfield Nursery. When you get the Prepper Pad, the device even scans vermin such as Rats and Crows, causing the player to believe there are zombies on the map when they may not be there. There are a lot of jumpscares added to the game, with zombies literally appearing through the woodwork and small cutscenes where the player will be jumped unexpectantly literally out of nowhere.

Unfortunately while the game has great atmosphere, it is plagued with many glitches, some game breaking.

Bad gameplay choices, such as animal meat having a 50/50 chance of healing or damage. Unable to use weapons when crossing waist high water. Or complete change of gameplay design especially later with the Arena level. Enemies are also very annoying. One will summon a horde, one is heavily armored, two are instant kills, one is projectile based.
If the player is killed they respawn as another survivor, but they will lose all their items they had previously obtained. The player will need to backtrack to their original location and retrieve it. Whether the player succumbed to a death or zombified. However if the player dies on their long trek back to their belongings, they will lose everything for good.
There's also No hud or audio options, and sluggish item management and reload animations.

If you can get this game cheap, try it for yourself. But remember this game is meant to be played with survival in mind, not run and gun action shooter like Left 4 Dead or Dying Light.
