X-Morph: Defense

This is the end-game boss. It is very durable and will take all 3 waves to destroy. On hard, you will need to collapse multiple tall buildings in order to extend the boss’s path to your core. As for attacking units, the good news is that there are only 2 routes you need to worry about - one from the north, and one from the south(east). The bad news is that these waves get very tough and you will need to commit a bunch of resources to stopping them from reaching your core. Use railgun towers on long, straight stretches of road. Focus on the hordes until the boss is fully repaired; you cannot do any damage to it anyway until it starts to move.

Like the others, this boss has multiple attacks. For the purposes of maintaining core health, the one you should be most concerned with is the missiles. You will want to build multiple (at least 2-3) anti-air (missile) towers to destroy incoming boss missiles. You may also need to use your ships missiles to destroy them, as they are the big, durable missiles. You can also build laser towers along the boss’s path in order to help destroy it. Besides the missiles, your main concern with this boss (after the hordes are destroyed) is your ship being destroyed, but this really isn’t a big deal. Most of this boss’s attacks are aimed at your ship, so you may die quite often. If the boss gets far enough along its path to the point it starts destroying your built towers, AND you still have hordes heading towards your core, you may need to quickly build/rebuild towers. Once the hordes are destroyed, you can repurpose the towers you have previously placed to either defend your core from the boss’s missiles, or attack the boss along it’s route. While attacking the boss, focus all your fire on the cockpit (center).
