In Tremulus you play as the father or mother of a family that survived the biggest supershear earthquake known to man. Cities are in ruins, and the only reason why your family survived is because of that camping trip you dreaded to go on. Your goal is to keep your family safe, from others and from themselves. Tremulus plays with the sanity of the playable characters, decisions matter. Your 9 to 5 office job never really taught you how to craft a proper wood axe, maybe you should spend some hours on crafting it; or maybe you should rush it, after all you can't risk not having enough time to start a fire to keep the predators away at night. Speaking about the night, you can't go to bed too late, otherwise you won't have enough time to hunt for food in the morning.
This is a screenshot of one of the first versions of Tremulus. It doesn't tell much, but we figured it'd be interesting to put it in.
