Notes & tactics

 * Due to the variety of enemies, it's suggested to make towers focus on certain types of enemy and players take care of the others, e.g. building solid Anti-air defences to be able to more easily concentrate vs the ground lumes.
 * The Rolfinator is a good tool vs ground enemies, although it is somewhat inacurate and not as good vs flying lumes.
 * The four Simo units can be utilized pretty well as either a bait that to force the aggressive enemies to stop and attack them, or as a last line of defense
 * It is good to have two or three Anti-air towers, or, if using one, to have it boosted by a Range spire and to be ready to use some more weapon action vs the air ones as well.
 * Wave strategies
 * Wave 5 - the 5 Mutators there are top targets. They can also be forced to walk an alternate path, since they cannot attack the core.
 * Wave 6 might happen to give more sweating than usually, since the Matriarchs are durable and might penetrate to the core. Some kiting and the Simo units can help.
 * Wave 9 is usually not too difficult, but care should be taken as falling from the map is relatively easy, so the player should be careful around the Hoverers.
