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.

Terrerohedron is a tower defence game with a lot of promise and is very addictive!

The concept is of a standard tower defence game but the map is in three dimensions, at first this can confuse and be disorienting but after a few games you will be spinning the map round and planning your kill zones with relative ease.

I normally like TD games that allow you to maze and shape the route that the enemy takes TH does not let you do this but gets very tactical as you can build in three dimensions, you place extendable blocks and then place towers on them or more extendable blocks. This makes looking at the map in all dimensions and then thinking of how you will build a 3d kill zone in an area quite rewarding.

There is not a huge amount of variety in the towers but the game does give 3-4 solid different play sets with towers you can choose from, it feels good when you enclose a complete section and then have towers that the bullets bounce back and forth to deal a crazy amount of damage.

There are also some great additions that should be in all TD games, a damage counter for each tower for each round and a total so that you can see tactics that work better or towers lagging behind. A huge choice in different target priorities for every single tower, this is something that should be standard in all TD games!

The game has multiplayer also and at a recent lAN 3 of us spent far longer than we would have thought trying to improve our game and win together. It is a nice addition to the game and adds a lot more hours of fun to it.

The game is definitely a small indie game that is what I hope the first edition, I got it on 95% sale and paid 19 pence for the game and so my following niggles not so much pan the game but are improvements I would love to see on the TH2 and I will pay more than 19 Pence for it!

The units that you try to destroy are multisided shapes and you take off sides until they have no sides left and they are destroyed. This makes it quite hard later on to identify how bad the threat is as one moving unit could end up costing you the game as it has more than 100 sides and thus all your lives. I would assume this was done for ease but even some that glow would be helpful.

The camera can get very disorientating and annoying to use, there are hotkeys to mark camera points and I recommend you use them. When you build an enclosed box it is hard to select towers to build.

In multiplayer even the fastest game setting is quite slow and makes it quite slow to play.

There are quite a few challenging difficulties and an impossible mode, this is not for the feint hearted and one map took me nearly 3 hours before I eventually lost, unfortunately most of the time in this was trying to spend the huge amount of money I got each round and it would take 10-15 minutes to spend it all. This is a small gripe as this mode is not to played that often but a quicker way to build would be nice. Also anyone who likes Minecraft would love this mode as it turns into a TD version of it.

All in all, this game is very interesting if feeling like it has a lot more to be unlocked at some point. I highly recommend getting it even if you just play some of the easier settings on a few maps, it makes you think and mixes up the tower defence area.

Oh and I loved the soundtrack, one of the few games I play with music on. Make Terrerhedron 2!!!

How in the f*ck am I enjoying this game?!
This simplistic tower defense seems like it has nothing to offer, but upon learning the possibilities lying behind 6-sided and 4-sided platforms, it gets full of crazy looking ideas. 3D aspect of it gives room for some very nice strategic planning. Great for coop, doubt it's any good for single player.

-The worst camera Ive seen in my life
-Chat is broken, stuck on capslock and there is no special characters and question marks
(Come on, just use steam chat m8)
Truth be said, amount of fun I had from cooping in this game overcame awkward controls, and upon getting used to them I really enjoyed it.

This is a must have for every tower Defense Fan! It took me a while to get used to the 3d profile and building the tower bases but the learning curve is part of the fun and challenge to most Tower D games. That is the case here as well. A mouse is a must in my opinion. If you are used to a track pad you could probably manage though. You must grind a bit to unlock towers and upgrades for them, however, they do a wonderful job of scaling it so you are grinding as you are learning and unlocking new tracks and such so It does not become a bore. It has some kind of 3-d effect option but I have no idea how that works. Someone more tech savvy will have to comment upon that. The game looks great without it.

The gameplay is pretty much the same as most tower d in principle. Different 3-d shapes move around a set 3-d track. You set towers in set places on the track and blow 'shells' - think layers- off of different shapes until there is nothing left and the shape is obliterated. You also have a couple choices of bases that allow you to build more than one tower in a spot. Use slows and offensive towers to kill all the shapes without running out of lives and you will beat the track. It also has trading cards and achieves for those that are interested. I had bought it at the super cheap price of .24 cents but it is one of the few games that I would say is worth the full price.

I have yet to play the multiplayer modes and will amend my review to reflect that later. Until then Game On!
