The following information is available to help you better understand some of the actions and menus available in Port Defender.
Gun towers: are the foundation of all defenses strategies. They are cheap to produce and make a great wall.
Rocket towers: are a powerful destructive force, but suffer from long re-load times.
Ping towers: cause no damage, but instead slow down enemies. No enemy is safe from its power.
Microwave towers: cause massive damage, but have a very limited range.
Nuke towers: are slow, have a limited range and cause the most damage.
For a graph of tower damage please see this PDF.
Bomb: Holding a bomb over a spot will cause it to build up strength, drain money, and cause more damage.
