Welcome back. Wondering what happened? The last stand was... well semi successful. You took out the first two waves, but four more were sent. The good part is that you were able to keep the crystals containing the information about the robots. You barely escaped with most of the crystals. Unfortunately, the thugs got two of them, just enough to know how to make the robots. Your mission is to get those crystals back at all cost. They may give us an edge in this war.
Good luck!
