Verdict
Cataclismo asks a question no other tower-defence game asks: where exactly does the wall go, and how tall, and does it have a parapet. You lay stone, timber and iron piece by piece, place archers on the tops and in the windows, and the Horrors that come at night test the shape of what you built as much as the towers on it. When the design holds, it is the most satisfying feeling on this list. When it fails you can see precisely which block gave way.
The campaign that arrived with the full release in March 2025 tells a quiet, grim story across a ruined kingdom and teaches the building system properly, mission by mission. Skirmish and Endless modes and a Steam Workshop full of fortresses carry it on. It is slower than most and wants patience; give it that and it gives back.

Towers 18 of 20
Archers, pikemen, flame and bolt throwers, plus the building blocks themselves, which are the real kit: stairs, buttresses, hoardings, gates and dozens of pieces that change what defenders can see and reach. Unit variety is modest; structural variety is enormous.
Lanes 19 of 20
Maps are canyons, bridges, ruined towns and cliff edges with real elevation, and the Horrors come from directions that make you think about the back of the fort as well as the front. The best levels in the genre for making the ground matter.
Waves 17 of 20
Day to gather and build, night to hold, and the nights escalate with climbers, brutes and acid-spitters that each punish a different design mistake. The campaign curve is fair; Endless becomes a slog of repetition after the fortieth night.
Economy 16 of 20
Stone, wood, iron and a population you must house and feed, which turns every daylight into a budget meeting. It is tight and satisfying, though the opening of each mission can feel like the same shopping list.
Longevity 16 of 20
Campaign, Skirmish, Endless and the Workshop, where other players' fortresses are the best tutorial in the game. The Old Kingdom add-on lengthens the story. Single-player only.
