Demo for Psychological Horror Game Toxoplasma is Out Now

Kuwait-based solo developer studio SimmeringConcrete are excited to reveal that the demo for their upcoming psychological horror title Toxoplasma is available to download now on PC (Steam).

Abandoned on a space station, develop your bioweapon.
In Toxoplasma, you are trapped on an abandoned space station, developing a bio-weapon that makes the infected hallucinate demonic entities. Spot any anomalous signs of infection before they kill you, complete your research, and unmask the conspiracy that brought you here.

The demo will introduce the player to the setting and unveil some early story beats. It will feature over 20 possible anomalies/hallucinations that may arise while the player is developing the bio-weapon on a day-to-day basis.

About Toxoplasma
Toxoplasma is a First Person Sci-Fi Horror game set on an abandoned space station where you're developing a bio-weapon designed to end humanity.

The world is falling apart. A rise of violence and misanthropy ravages the Earth, but your space station is not safe either. Every day you work towards a bio-weapon made to wipe out humanity in the most brutal way possible.

Anyone who is contaminated hallucinates demonic entities that torment them until they die. You must complete its development before your hallucinations kill you. You must figure out why you are trapped here.

The infection manifests differently each playthrough. No two experiences are identical, ensuring a terrifying experience for newcomers and veterans

Features:

  • Identify anomalies before your hallucinations become fatal

  • Progress your bio-weapon research

  • Distinguish reality from demonic hallucinations

  • Piece together the conspiracy behind your mission through scattered evidence and radio transmissions

  • Your choices shape multiple endings, including a hidden ending
