Hey, seems the Full House Badge is broken, the badge did not track and even so i played and completed all the 8 chapters and submitted my score, but with no sucess. Took to me 3 hours. If you want the badge you need to screenshot the last scene and report missing achievement, at least for now.
Yes, like other comments i found, a easy way to complete the 250k total dmg challenge is putting 4 interlocked shock towers(guard tower originally). i got 434k in the first try.
I really enjoyed the game, needs a lot a practice to win I3. Lost Sector took me 5 days to complete, playing 1 hour each day, advancing little by little. At the final the level became easy.
I think the secret is not overdo and not give up.
For the epic boss: at start press x and stay on the top screen, u will colide with him, keep pushing him up with your ship so he will never be able to enter the frame. Keep doing this, firing and pressing 'V' and 'F' when needed and u will be able to kill the final boss and he will never fire one single shot. I just buy the ultra bomb and dark energy from the legendary shop.
@GamerCubed Its not only level up fast. You can buy krowns, upgrade everything, rush constructions, etc... Its ok to have some advantages for whom is willing to support the game, but not this. Token dependent, like the first one.
After you get the easy badge, keep buying/deleting the work table. Quickly you get the medium badge and quiclky you get rid of this token oriented game.
