How many GB is Probability 0?

0.02 GB

That is less than the typical Platform game, which needs about 2 GB.

Leave at least 6 GB free: games need headroom to unpack updates.

The figure is the storage Steam lists as required for this game, not a measured download.

Probability 0 is a downward-scrolling infinite arcade platformer. There are a million ways to fight for survival. Descend: as you combat the darkness, improve yourself. Build yourself up as a star-thrower or a teleporting menace. Learn to traverse the pit's many dangers, from threatening monsters to unforgiving gravity. Walk across spikes that once frightened you. Punch through walls that would have doomed you. You'll never be invincible.
