Game modes

Cataclismo features four game modes:

1. Campaign is the game's main story. Units, pieces and buildings are unlocked as the campaign progresses through missions and The Book of Insight is available. Each mission has different mechanics depending on the mission type.
2. Skirmish contains two missions that last 4 nights each: Forgotten Glade and The Torrents. Everything starts unlocked but needs a high enough Prosperity level.
3. Endless mode features procedurally-generated maps of the chosen terrain. Only the most basic things start available, and everything else has to be unlocked using points. Progressively harder waves of enemies appear each night, with grant points. Waves 1-4 grant one point, waves 5-9 grant 2 points, the rest grant 3 points. There are resource caches scattered around the map but the biggest caches are guarded by Broodnests.
4. Sandbox mode allows all buildings, units and horrors to be placed instantly and for free. There are no resources, maintenance or nights and there is a menu to enable invincibility or remove all horrors.
