Steam Store description

Lost Prototype is a ‘game’ created by an unnamed developer. You are asked to try this game...or ‘prototype’ and find a way out. Something is hiding in this prototype or someone, we don't know. Just avoid getting caught. This game lasts about 10 to 20 minutes and contains flashing lights and sometimes loud noises. (Lost Prototype is a test ‘game’ to train myself on Unreal Engine and especially to make my steamwork account and stuff).
