About Allergenium

Allergenium is a survival game set in a world where processed food has triggered severe allergic reactions, turning sick people into zombies. The surviving people have each been infected by a different mutated allergy, so you must watch what you eat and drink while trying to stay alive. You and other survivors travel in search of a scientist who may be able to help humanity return to normal.

A world in crisis

The outbreak has left cities and neighbourhoods devastated and abandoned. Before it began, the scientist was ridiculed for opposing access to chemical food; rumours say he disappeared on an unknown land with a group of people. You have the chance to explore this changed world and try to alter humanity’s fate.

Survive together or alone

You can play solo, with friends or with other players. Other survivors may be friendly or hostile, so you must decide whom to trust. In the open world, you choose where to go and what to do.

Game modes

  • Team Deathmatch: two teams fight using whatever they can find.
  • Chillout Mode: use grenades to throw zombies around and draw from an unlimited supply of guns.
  • Zombie Waves: play alone or cooperate with other players to survive waves of zombies for as long as possible. They can spawn anywhere.

Build and develop

You can collect materials from places such as abandoned homes, cars and garbage, then craft items for survival. Build anything from a fortress or a hidden shelter to a quiet cabin in the forest, and customize your survivor with T-shirts, pants, shorts and hats in different colours and styles.

You gain experience and invest it in five skills: health, armor, damage, agility and knowledge. The description also names cardio, hungry, thirsty, immunity and finder as five additional skills. Your allergy is another danger to manage: monitor your body when eating and drinking, and react if you notice something wrong before it is too late.
