X-Morph: Defense Review (TSA)
TSA writes: "Earth is under attack once again, with pesky aliens wanting to strip the planet of it’s natural resources. This time though, just for a change, it’s you who are the invading force. Huge harvester spires are dropping across the planet and it’s up to you to defend them as the humans mount attacks by air and land, and occasionally throw in a huge boss mech as a last resort."
