At first, I thought this was a game where I could complete levels easily with a few lasers strung across a level, but I was wrong. In order to win I had to stack massive towers of plasma cannons, with multiple turrets and blocks towering across the map like a minimalistic Lego set of a futuristic battlefield. Even when I kept losing, I wanted to keep trying it again. This simple tower defense game evolves over time and becomes shockingly addicting.

Tower defence games often follow a formula, whereby you obey certain rules and fulfill certain criteria. Good tower defence games make this process happen invisibly and provide an experience that is both addictive and challenging, games like the seminal Defence Grid, which is considered the benchmark upon which all other Tower Defence games must be looked upon.

Comparing Terrorhedron to a Tower Defence game isn't really possible, because if Tower Defence is a formula, then Terrorhedron is algebra. It is mathematical purity and brilliance, expressed in abstract form. In most Tower Defence games you have a fixed path upon which the creeps will run and try to get to your base, you may be able to mess with this path by placing towers down, or you may have fixed locations upon which to build your towers.

Technically both apply here, but where it departs from the norm in this case is that the tower build points are merely bases, and from there you add lego like snap connectors from which towers can grow, tree like from the root node. Simple turrets become crazy branch and leaf arrangements with dozens of turrets hanging off of them, all pointing in different directions, programmed with different priorities and having different lines of fire, and in this game, LOS is fully obeyed, so you have to pay attention such that you don't obstruct your own towers.

The game takes full advantage of this, with levels working on every single plane of a three dimensional maze, often weaving complicated, tangled paths over cubes or more complex surfaces, allowing you to maximise your opportunities if you're clever and are willing to be imaginative, and that's the key bit, because you can use the snap connectors freely, the only limitation is really funds and how crazy you can get with the tower layout, want to build mighty archways with laser turrets hanging off? Go nuts. I just did for a section of the first level, and it worked beautifully. Here, you -build- the towers, step by step.

With such an expansive canvas, the aesthetic comes as a relief, being clean and abstract, minimalist but without looking amateur, game looks slick, well rendered, and has a thumping soundtrack, and doesn't suffer any framerate issues, regardless of what mayhem is going on at the time, and the clean design of the level layout allows you to keep focussed on the action. Doing the tutorial is mandatory this time, because Terrorhedron requires you to adapt to the fact that this game will have you building corners, arches, bridges, and all kinds of things to create your own defensive setups.

The only minor complaint is the fact that towers are gated behind some sort of "experience" wall, so intially you don't really get the full Terrorhedron feel, at least until you've unlocked the snap towers, but once you have, the game opens up dramatically, and then the levels become your toybox.

Tower defence is maths, Terrorhedron is the degree course.

A new twist on the classic tower defence genre. Both challenging and entertaining, Ive been enjoying what ive gotten to play so far. Towers, upgrades, and maps unlock as you gain xp, and are persistant between maps. Upgrades are pretty standard with the level 1,2,3 system, however the level 3 upgrades seem to completely change the function of the tower, making for some new and interesting strategies. Cant wait to try out multiplayer! I strongly suggest this for any TD fan out there.

An addicting, challenging tower defense game with a simplistic though pleasant art style. Can be played alone, but is also a multiplayer game. I've played with a couple people, and it's a lot of fun to have people to talk to and figure out strategies with.

There is a fairly large variety of turrets you can earn, each with 3 levels you can upgrade to eventually. There are also 4 and 6-faced blocks that you can build structures with to place turrets on, allowing you to branch out from the specified, sparse turret spaces and make some really awesome stuff. There's also quite a few maps, all with multiple difficulty levels.

Definitely worth buying. The only downside is the in game chat system. You can use it, but it's not very smooth. You'd be better off hopping on Teamspeak.

Immersive 3D tower defense game. If you are going to get this, note that plasma tower is OP as ♥♥♥♥ and is the only tower you ever need to ace any map.

I do not understand how come those bad games on steam ? Just a terrible game, not really understand the control off game, Music ugly, And cost 10euro? For that kind of money to be 100 times better and buy Kingdom Rush, Radiant Defense, Orcs Must Die! !!! Terrorhedron DO NOT Buy it, you can find a better game. 0/10

This is almost a yes. Cool concept, but I've noticed some bugs. Achievements are titled wrong, some placement spots are broken, the last level has no collison for the ground.

Such a beutiful game, it's simply breath-taking, and not because of what the game shows you, it's what you end up with at the end of the level, the tree of turrets you built from scratch and became something so powerfull it could witstand the countless polygons that came to destroy(?) you ... it's unique


Basically it's a tower defense, but 3D... but not the 3D you're thinking about ;)

if you dont like tower defense games, i would just give this one a shot. Theres alot of stratagy behind this, espeically if you have 4+ people playing. But that fact that you need someone to almost manage your group gives this tower defnece an edge in my opinion. Everyone has to work together, deciding who will build, upgrade and save for that nice plasma turret to carry you to the end of the level. I highly recommend this game if you like co-op games and this can be played over hamachi which is amother plus in my book

Very fun game. The multi-directional building blocks that you can build turrets or more building blocks off of is a really unique offering and makes for some cool strategies. The graphics seem pretty simple but it gets quite pretty when you've got a plasma beam rapidly peeling off layers from the enemy. The music is also nice and adds to the retro style the game has.

The online co-op works well and is a pleasant addition, every game is more fun with friends.

Worth it at full price and a total steal if gotten in a bundle. Probably the best out of the dozens of Tower Defense games I've played.

Great game. I didn't think I would like the 3D aspect, but It grew on me quickly. Intuitive controls. Two complaints: Things going out of focus that should be in focus, and no 'prospective range' IE before you buy a turret see where it would be able to shoot. Played once got to lvl 20 one piece got through, and hit me for 60+ 7/10
