The trenches of World War One weren’t exactly a Saturday afternoon picnic, but in ZWar1: The Great War of the Dead’s alternative timeline, they’re so much worse. Ether Games’ mobile first-person-shooter, cum strategy hybrid, takes the term ‘horrors of war’ literally; select players can experience them first-hand, now that the game has entered closed beta.

Bullets and mustard gas and aren’t the only things you have worry about in ZWar1. The game takes place in a diesel-punk version of the WW1 era, where a villain known as the Black Reverend has used ‘Auferstehung Gas’ to raise an army of weaponised undead and opened portals to dimensions full of Lovecraftian horrors.

It’s trench warfare with added undead and extra-dimensional monstrosities roaming the battlefield. The action takes place from first person perspective and combines tower defence and light RPG elements, with a wave-shooter.

ZWar1 visuals bring to life backdrops including trenches, muddy battlefields, destroyed townships and interdimensional portals.

Using authentic WW1 weapons, it’s your job to hold defensive positions at these locations. You and your squad face an onslaught of undead and eldritch creatures; gun them down, trap them on barbed wire, impale them with bayonets, blast them with grenades, send fighters against Winged Horrors and drop artillery barrages on Great Ones, all in the hope that your platoon will live to see another day.

If Battlefield 1 mashed up with Lovecraftian fiction and tower defence themes sounds like your cup of Cthulhu, you can sign up for ZWar1: The Great War of the Dead’s closed beta via the developer’s official website now. Testing is underway for iOS users now and will be coming to Android in the near future.
