Dec. 2025

While the game is built mostly around siege defence and save scumming, its a very fun game imo. The story is also pretty good, and the campaign is pretty challenging especially Defense of Hogar. However, what I like the most about the game is that buildings can strategically be placed and "combined" with other structures. For example you can place Oxygen Pumps on certain buildings like the citadel and barracks. You can stack Shacks together into a condo of some sort. With enough creativity you can create buildings that not only looks cool but also serves a function. Its such an innovative mechanic that I feel like more strategy games should have such option tbh.

In my eternal yearning for another They Are Billions, Cataclismo had long festered in my backlog; a half-built fortress waiting to be pieced together as I greedily munched on scrap of patch-note after scrap of patch-note. Arriving late to the celebrations, delayed by wrist injury and RSI-compatible mouse, I found a curious amalgamation of ideas and undeniably beautiful art, a feast for the senses wrapped around a somewhat clunky skeleton of colony-building and swarm defense. I tinkered with my digital Lego blocks, trying to convince myself that efficiency was fun. Tinker leads to tedium, and restrictive level design occasionally steals creativity, forcing a strict methodological work pace. Slow until it's not, then rewind to do it again. Cataclismo is an idea I'm thrilled to have experienced, but one that I will likely not return to after my 10 hour shift. 3/5

A decent city-builder and RTS hybrid with impressive visuals and sound design. You play as Lady Iris, an overseer of a human colony surrounded by deadly mist and monsters. The tone, art style, and setting of this game is really appealing to me - a minimalistic rendition of a post-apocalypse with body horror is surprisingly unique and utilized very well. The main gameplay loop of this game is rather simple. In regular levels, you are tasked with defending a settlement's citadel building or some other things that need defending. You will then need to gather materials during the day in anticipation of the monster's attacks at night. Resource and time management is crucial. Other than facilities that let you farm and build things, you'll also need to build fortifications with stone and wood. An interesting and novel mechanic in this game is wall toughness. The higher a wall is, the more HP it has - along with slightly different appearance. Managing and balancing between building and gathering during the day will fire the cylinders in your brain. The enemy hoards during the night will then put your preparations to the test. The number of monsters on screen at a time is impressive. And it really feels like you're being swarmed, not by organized forces, but an overwhelming mass of feral flesh. And on harder difficulties, you might need a few retries on each level to survive. There are also some missions that play out like a linear adventure. These are usually major story points with some secrets for you to find. Completing these secrets and side objectives give you additional skill upgrade points, which are really great. Other than the campaign, you can play the city-building levels in their own set challenges without story-gated mechanics in Skirmish mode, or do so endlessly in the Endless mode. There's also a custom editor that you can make your own level, so go wild. What caught me off guard for how good they are - are the sound designs and still-pictures cutscenes. The sound of building stone walls, horrors making exacerbated exhaling sounds, and arrows whistling through the air are some of my favorites. The art for cutscenes are also great and shows off so much of this game's minimalistic but manacing style. If there's going to be more games with this scope of design, I'm really looking forward to it. Overall, a solid RTS game with city-building gameplay that requires good resource management. It can be pretty difficult if you're not used to this sort of game. Luckily there's multiple difficulty options, in case you're not up for challenges (thank you story mode that allowed me to actually finish this game). I recommend grabbing this on sale.

I am happy that this game features a singleplayer campaign (I bought without checking first). Played the entire thing at normal difficulty, and just loved it. Building things is very satisfying. Having the rewind mechanic (a quick-load with extra flair) also adds to it, because during waves you cannot savescum so you either have to commit to your decisions or do the whole wave again. In most levels it's hard to get the economy right. Well, at least I did it all without looking online for a meta / optimal way of doing things, and while doing so I realized at my own pace what worked and what did not. I've bought it at full price, after getting a random recommendation from some Youtuber. No regrets at all, on the contrary I do recommend it if you are into strategy / management games.

Would prefer that for campaign missions, after the 4th Night, give an option to continue playing it as Endless.
