Our take on Vaccine

The bounce point arrives after returning with the vaccine: without solving the house’s mystery, the infected teammate relapses and another randomly rebuilt house appears. Players expecting the first successful retrieval to conclude the rescue may hit that repeat cycle immediately.

What is Vaccine?

Vaccine is a survival horror game inspired by titles from the 90s.

Players choose between two members of a bio-hazard response team, each with different abilities. They enter a strange house populated by dangerous mutated creatures and must find a vaccine for an infected teammate before time runs out. Bringing back the vaccine does not end the cycle: unless the house’s mystery is uncovered, the teammate relapses and a newly rebuilt version of the house appears. Actions grant experience points that can be spent on skills, adding a tactical element to encounters. The game combines time pressure, combat, character development, and repeated searches through changing house layouts.
