Soldiers, here is the ultimate guide to bring them democracy!
1. Wait until you got 50 credits, then hit the flower on your lower right side.
2. Let them come...when the music is up to let the beat drop...hit the flower again followed by the airstrike on the lower left side!
3. If they survive and are still to close to your home, hit them with the hurrican.
4. Bring up some soldiers (at the moment you should have almost fast enough credits like the counter for the girls is ticking)
5. When they are too much, drop the Hammer and smash them.
6. Use your shield if needed.
If you got a new girl, let her be the first lead. So you can see her animation at the lower middle screen.
Note: the last girl you got don´t have any animations in field yet.
You can repeat this basically in every level, once you got the archers (about 7-10) you kill almost everything with a 2-hit. Warriorgirls just for measure. But when you do, use the centaur girls.
