Picked it up on the steam summer sale and have had a blast playing with my buddies. The camera might take a little bit to get used to but if you've messed with many game editors its simple and easy to use.

I love this game. I love the good selection of retro music. I love the game play. It is very replayable. I like to replay with different strategies. I love the geometry of it rather than gore in so many other games. This is a very fun game. It has enough levels to be a very fun experience but I wish it had 30 more levels as well designed as the ones already in it. I do recommend this game if you like tower defence games. Its a solid fun experience.

Pretty good tower defense. Honestly, I don't find it as fun as others but it's still worth a play if you like the genre.

The Game Itself Was Very Good But When I Finished It I Thought That There Would Be A Sandbox Mode To Test Myself,But Sadly It Didnt Have It.It Was Definetly Worth The 0.49 Cents.This Game Needs A Sandbox Mode And A More Not Complicated Way To Play With Your Freinds.And There Should Be A Mode Where We Can Send Our Own Enemies Not Custom Just You Could Send Any Level Of An Enemy To Test Your Limits.And Plus I Think This May Just Be The First 3D TD On Steam,So Congrats On That! And Please Pleas Just Please Add A Level Editor And A Map Shop To Download Other Peoples Maps So You Can Use Them,Also Please Add More Levels To The Turrets And More Turrets And Add More Turret Platforms To The Maps.

If The Developer Reads This And Updates The Game I Would Be Happy!

Definitely a fun game, the co-op worked good on the first try. A few bugs hinder the fine gameplay. The 3d aspect really gives a somewhat new approach to this tower-defence, howeverthere is a lack in depth for the different turrets and upgrades. A double damage upgrade simply doesn't give a wow-factor. I would have wanted to see some unique turret designs and upgrades but apart from that this game is worth picking up for a couple bucks. 10+ hours of gameplay is a great amount for this low of a price. With a couple tweaks and upgrades this could have been one of the best tower defence games till now. I like it.

An astounding tower defence game for people with tastes up the alley of Kerbal space and the like.

However, I haven't at all been able to get the multiplayer working with a decent amount of time. Port forwarding, VPNs, nothing. So don't buy the game based purely on the co-op.

Just got this game today and am already hooked. I thought this game looked interesting due to the fact that it was unique not like the other survival games. This game has boht an heir of beuty to it but also an heir of emmense fear due to the fear of what could be lurking out in the water away from you. Get this game!

Tower(Defence) = Guns / Turrets + Bullets(Lots)*Missiles

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.

Wait, what, I have root? ... I have root... muwahahahhaha. I HAVE ROOT!

In this case you do have fixed starting locations from which to build upon, 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. 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.

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.

Depth of field? Check. Abstract polygons? Check. Chiptunes? Check.

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.

Enemies in this game are represented in a similarly abstract manner, simple three dimensional shapes with various colours representing their health, it keeps things simple and allows for absolutely ridiculous levels of enemies on the screen at once, when combined with the insane combinations of bases and towers, this can turn into an exceptionally busy game in a real hurry. It keeps scaling as you go, so when your carefully constructed strategy begins to falter, you may find that you have to re-engineer and expand to ever greater feats of lunacy to keep the enemies at bay.

Terrorhedron University is open, enroll today.

In Terrorhedron you take pretty much every principle you've learned from other Tower Defence games and then extend and amplify those concepts, turning them from basics to pure, abstracted concepts. In effect, the game takes the genre, strips away all the things that aren't needed and then refines what there is and adds a few key elements that in turn fundamentally require the player to abandon the comfort zone of "just build a tower", because it's never just a tower, not when you're perpetually adding and extending it. Tower defence is maths, Terrorhedron is the degree course.

Verdict : Essential, even moreso if you are a Tower Defence fan, or a Tower Defence player looking to improve their skills in the genre.

Fun game. Got my money's worth out of it.

Have noticed a few reviews hating on the art style. I like the retro 3D look. Does not distract from the gameplay.

Will continue to play higher difficulties and figure out new strategies.

Wish there was a construction set and / or Steam Workshop for more levels.

A simple game of polyhedron genocide in a 3-dimensional setting. The learning curve is odd, but you eventually learn all you need to know and take off.

Plus, I got it on sale for -$1.51! A total 151% off! How can I NOT give a game this cheap a 10/10?

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.

Pros:
- True 3D tower defense: geometric placement of towers is important
- Simple shaded graphics is easy on the eyes
- Open-ended gameplay with infinite number of solutions

Cons:
- Indie game that is rough around the edges
- Balance issues: some towers are not worth their cost
- The EMP Turret, which slows enemies down, works permanently after one shot. That is never explained though and I wasted a lot of time building multiple EMP Turrets until I figured it out.
- Medium and Hard difficulties are available from the beginning, even though they are impossible until you unlock additional towers.

Final note: I've thoroughly enjoyed Terrorhedron. Part of its charm is that there is no fluff. The graphics are purely practical, so much so that the enemies are simple shapes. Everything on the screen has meaning that is relevant to gameplay, which allows the gamer to quickly become immersed in it.
