About
In Crystal Tower Defense you stop an endless amount of crystal-type enemies from reaching the portal to Earth. To achieve this goal you can build your own labyrinth using turrets and walls as well as selling obstacles on the map. You will need to stay alert since the enemies grow stronger the longer you defend the portal. Upgrade your turrets and alter the labyrinths layout to adapt to the new challenges.

Enemies will follow the path YOU create! This challenges you to experiment with different labyrinth layouts. The map, with its randomly generated obstacles, will tickle your strategic thinking every time you jump into a run. Remove map obstacles to open up new possibilities during a run and restructure your labyrinth to use each of your turrets to its full potential.

As you progress through the stages, you can unlock 10 turrets.
You can upgrade each turret's main stats in a run. The required gold is earned through destroying the enemies.

Use 6 different abilities to support the turrets in your labyrinth and fend off the enmies.

Each enemy has a chance to drop crystals! These crystals are your primary currency and are used to unlock new and different turrets, as well as permanently upgrade them. Completing a stage rewards you with a big crystal that holds permanent upgrades for your turrets! You can equip these upgrades in the armory.
These big crystals can only be obtained playing the game. After each stage you get rewarded one big crystal. To claim them, you need to end your run manually, if you run out of lifes, you lose all your gathered rewards.
The higher the cleared stage is, the better are the rewards. The drop chance of each rarity, per stage, can be found in the menu.

The forge gives you the possibility of merging your hard-earned upgrades, to achieve bigger and better bonuses. Combine a multitude of possible items and find the best possible upgrade path!
Combining your upgrades always results in a better bonus. Combine multiple of the same, to decided the result type.

Nice to see a solid tower defense game without paying for every tower and level. :-) Pure gaming! I like the dynamic approach: Building up walls and create a new paths.
Great little tower defense game. Not perfect but fun trying to unlock new cards to upgrade towers!
super cool :) really diggin it
Ein schönes Game,.. ohne Spaß ? Oder verstehe ich hier etwas falsch ? Natürlich hat man hier Spaß beim Strategischem bauen und upgraden. Man erhofft sich mit dem Loot Verbesserungen für die Türme bauen zu können. Leider zeigen die Verbesserungen nur sehr wenig Wirkung. Und was macht es für einen Sinn,.. wenn man immer verliert oder Aufgeben muss ? Entscheidet selber,..
Also erstmal Vorweg: Das Spiel ist nicht schlecht. Was es (für mich) unschön macht, ist, dass es recht flach ist und das Balancing so designt ist, dass man EWIG rumtun müsste, um alles freizuschalten. Dafür fehlt einfach die Tiefe. Ein Beispiel: Bei jedem 10ten Level kommt ein neuer Boss mit neuen Fähigkeiten und in den darauf folgenden Runden neue Mobs mit neuen Fähigkeiten. Damit man etwas gegen die neuen Fähigkeiten machen kann, bekommt man einen neuen Tower. Doch diesen bekommt man nicht nach dem Boss kampf in Runde 10, sondern man muss noch einmal Runde 11 überstehen. Ok, dass alleine wäre einfach nur unlogisch, doch das bei dem Turm für den Tower als Beschreibung noch geschrieben steht: "Erreiche Lv10", anstatt "Vollende Lv11", hat mich schonmal 5 Extra Spiele gekostet. Ich wollts wissen :) Und dann gleich noch was: Keyboard Settings sind wohl geheim. Es gibt kein Menu wo man nachschauen kann. Ein paar Tasten habe ich durch try&error rausgefunden, aber was soll das? Nervig. Und noch was: Man kann die Settings der Türme nicht kopieren&einfügen... Wollt ihr uns eigentlich ver...? Und noch was: Die drei Optionen auf die man die Türme einstellen kann, sind einfach zu wenig. Ich empfehle den Spieldesignern das gleiche wie dem interessiertem Leser hier: Kauft euch lieber Nordhold Origins.
Really invokes the spirit of the classic TD-Games and makes you forget the time. Keeps you hooked to explore the upgrade options and all the turrets , of which there are alot of. Difficultiy scales well and keeps it interesting and really pushes you to try to optimize your map building and tower placement. The randomized maps always keep it fresh even when you feel you discovered the perfect layout. Very fun!
E' un bel gioco, se vi piacciono i TD è probabilmente uno dei migliori al momento
A good mix of classic and innovative.
I love TD games, but this one is not worth my spare time. Way too expensive for what it has to offer and very boring.
Très tactique
