What is the goal in Monster Underground?
The goal in Monster Underground is to help an alien monster evolve into one of the greatest monsters on earth. You start as a small worm and grow by feeding, while the military tries to destroy you before that happens.
Who is hunting you in Monster Underground?
Soldiers and the army are trying to destroy you in Monster Underground. They are the constant threat throughout the game, which makes every trip toward food a calculation about exposure rather than a free action.
How does evolution work in Monster Underground?
Evolution in Monster Underground is driven by feeding. The more your monster eats, the more it grows, and that growth gradually shifts you from something easily destroyed into something capable of confronting threats directly.
What do you start as in Monster Underground?
You begin Monster Underground as a small worm. That early fragility is deliberate, since it forces cautious movement until enough feeding has taken place to survive contact with the soldiers hunting you.
Does Monster Underground get easier as the monster grows?
Partly. A larger monster in Monster Underground can absorb threats that would have destroyed the starting worm, but the military response scales alongside it, so the danger shifts rather than disappearing entirely.
