About This Game

The Game

Zona Pugna Exitium, or Zugnaex for short, is Latin for the Battle Zone of Doom. Also known as Doom Battle Zone. It's classic FPS gameplay with a unique multiplayer experience.

The Story

In ancient times, a powerful demon, known only by the forbidden name Zugnaex, was imprisoned by forgotten gods to prevent the destruction of reality itself. The prison, an interdimensional cage bound by immortal blood, is impenetrable, indestructible... and smells really bad. However, the gods did not realize there is one way the demon can escape. If any mortal speaks its name perfectly, every single little tiny syllable, the demon will tear through dimensions, bypass its eternal prison, and return to annihilate humankind. It’s game over and humanity is out of quarters. But Zugnaex has never faced a foe like you. Only you and your friends can defeat the demon Zugnaex and save humanity.

The Battles

The online service hosts many battle variations. Here are some that you can experience:

A Demon a Day - work together with your friends to defeat demons. Each kill counts for all active players but be careful as friendly fire is enabled. Help each other to get the highest score and become a demon slaying legend.

That Guy - complete different mission objectives with your friends but there's a twist. The demons are powerful and the marines may succumb to their will. Who is your ally and who is your enemy? Play to find out.

Pennies from hell - demons drop pennies and you collect them. It's a PvP party where the best players will wallow in the riches offered by the denizen of hell.

Ready or Knot - it's time to play hide & seek but old school FPS style. It's PvP where all players are against "it." If "it" survives the other players explode just like in the movie.

And many more including speed running, co-op adventures and the ultimate confrontation with Zugnaex itself.
