Current build does not currently have a win condition as it is an early prototype developed for the game jam. The idea is to give the feeling of hopelessness as the infestation spreads. The full release will still not have a "win" condition, as you are fighting an endless battle that you will always find yourself on the losing side of. Narrative and story direction will give the game a more defined play style, but it is still based on end conditions not win conditions. It all comes down to what you choose, and how your story ends.
