This level also doesn't need too much explaination. I just get a shitload (11) of Mortars on the little island all shooting at the Fountain of Youth (This is also the big difference compared to Cortez's run and caused quite an improvement amount). Those guys cause a lot of damage against buildings much more than ships can do (Except the Monitor maybe, but I can't get that one), and they're cheaper, too. Even when the ships that are available to me in this level are upgraded, they can cause about 1/4th of Mortar damage (A Mortar does 500 damage), so the choice is obvious :) The annoying thing is that Mortars are very retarded. There were always one or more Mortars that did not start to attack the Fountain of Youth when I told them to, and so it also happened in this run. But because it always happened I was a bit used to it, and in this run I very quickly noticed that one of them didn't start to attack. In order to make them attack again you only need to move them a little... That's about it for this level. I also use the Fixed Gun and the 2 ships that I can control to attack the Fountain of Youth, and all these units combined turn the Fountain of Youth to scrapmetal in no-time.
