Fortress
Troopers, this is a fortress defense mission: survive 25 waves and hold the line for as long as you can. Remember to leave feedback after the mission. This scenario pushed my system to its limits, but it is beatable.
Be mindful of the support buildings you choose to deploy—you have a limited amount available. I strongly recommend saving some for the later waves when the pressure intensifies.
Good luck, troopers. The survival of the fortress depends on you!
