Click the unit icon to send that unit out. The arrow at the top pulls up and down the upgrades, and the arrow below the units pulls up the second list, and to get back up, there is one above the units. You'll have to figure out the rest on your own.
the only things I changed from the original game is that everything costs $1, don't let the signs deceive you. or do, I don't care. I also changed the colors of the units so its easier to tell them apart. (the medics actually cost $750 dollars by the way) if you see this then comment "kaBoom"
