Notebook Defense is a must for all fans of Tower Defence games. In front of you, you will find a map, which constitutes the playing field and on which you see can a green trail. The playing field has an entrance, which is marked with 1, and an exit, which is marked with 2. When the game Notebook Defense starts, various enemies will rush into the gaming landscape at the entrance, and you have to prevent them from reaching the exit by any means. As the chief strategist, you now have to place auto turrets on this field, which will fight your opponents. The turrets differ in their shooting speed and in the ammunition that is fired here. You can certainly imagine that large-caliber weapons do more damage than small caliber ones. On the other hand, the big guns do not allow you to shoot as fast, and the enemy may already be out of your reach at this point. Therefore, it is especially important to calculate exactly where you want to place each one of the turrets. In the case of the first enemies, this is still an easy matter. For them, you can build a maze with the guns, but this tactic will fail for later enemies because they fly straight above and over the towers. Here, you will need fast guns with a long range. Overall, there are six different types of guns available to you in Notebook Defense, which obviously differ in their cost. The ice cannon is particularly interesting, as it freezes the opponent for a short period of time, while the other towers fire on. Furthermore, you can also upgrade the towers in order to get a higher firing power, or you can resell them in order to be able to buy other towers. As you can see already, the game Notebook Defense offers a lot of setting options. If you think that none of this is all that difficult, you can simply choose to increase the level of difficulty. The levels of course become more and more difficult and demanding as well. One really cool thing is the maps editor with which you can design your own landscapes.
