Cataclismo is a real-time strategy tower defense video game developed by Digital Sun and published by Hooded Horse.
In the game, the player is tasked with collecting resources and constructing a stronghold using a building system inspired by Lego during daytime, while defending against large hordes of enemies at night.
During daytime, players must also invest in technology to unlock new troop types, and expand their strongholds with new buildings, traps and facilities.
[6] The defense buildings constructed will slowly crumble when they are damaged, and sometimes collapse completely, decimating both the player's allies and enemies.
Following feedback from playtesters during the game's early phase of development, the team made an effort to ensure the most effective buildings were also aesthetically pleasing by implementing a system that allowed players to place decorations which provide additional gameplay perks.
