# Choose your Pilot and Mech! Prepare to build your city defenses and manage your equipment. Face the incoming alien threat, known as Angels, that traveled interstellar space in their seed pods and arrived on Earth bringing death and destruction. You will need to upgrade your mech, manage your weapons and equipment. Build the perfect deck combination and survive all the incoming Archangels. You can also build your city defenses and with appropriate funding create the perfect city fortress. Just don't forget to give enough time for the population to evacuate. Once the buildings are empty, you can use them as part of the offensive, to block incoming attacks or even crush the Angels between buildings.
