I will say the stats could use work. The FN Five-Seven pistol, for example, should have WAY higher damage and penetration. The way that round is designed means it's actually more similar to a rifle than your average pistol. The rounds fly WAY faster, which means much more energy transferred to the target.
After I have all 3 ion cannons, I just tend to stop making troops and let the enemies die until I have 450,000 gold to make 3 super soldiers and just win that way. It really only takes 2, but 3 looks cool.
Another amazing addition to the series. I do think that you should be able to burn the zombies off the back of your vehicle with your boosters, obviously at the cost of some of your boost. I give it a 5/5 because it is exactly what it's trying to be and it's amazing. :)
Tip: If you want to get the achievement for breaking the elevator but you don't want to be stuck because you broke the elevatore, then repeatedly hit the elevator on the LAST elevator on level four, you will fall straight into the end of the mission so no harm is done!
Lots of misspellings, but that hardly matters in a pirate game. Probably intentional.. I don't know. However, this is a very fun pirate game. You even had commerce, though I think you should need to use commerce more. I gave it a 5/5 and made the game a favorite. Pirate games have a special place in my heart. :)
Destroying Earth is a fine idea. Until you think about it. Even from the moon, you just doomed yourself. That Earth was what kept you from floating away and colliding with an asteroid or star. Amazing game though!
