Injection

First-person horror puzzles

Injection is a first-person horror puzzle game set in a massive factory. You play as Lena, a 20-year-old pulled into an artificial intelligence training course against her will. To progress through its three sectors, you inject yourself with serums that change your abilities.

Serum-based puzzles

Each serum changes something about Lena, such as her speed or jump height. You can use only one at a time, so solving a puzzle means choosing which ability fits and deciding when to switch to another.
