Sensor tower

These towers would be made useless under most circumstances, but because of introduction with otherwise invisible insectocytes, it is essential in waldgeist levels. It does no firing at targets, and is expensive for what it does do. However, if you have amp towers to boost it's range the sensor can cover an awfully large part of the map, and so only one or two are needed. It is important that you build sensors a good distance apart from eachother as there is no benefit from range overlap. Use in small number in any waldgeist level as insurance against the appearance of invisicytes, because if you fail to build one in time you are likely to die(or more accurately have your' mining base destroyed). Don't underestimate invisicytes even with sensors up and running and covering much of the map; they have similar if not identical in stats and numbers to their' none camouflaged equivalents.
