SRRD is a hybrid of Strategy Railroad Logistics, RTS resources and base build, and Tower Defense. The setting is fictional, but with a historic middle 20th century feel. Coming soon: there will be an episode one release of the game, which will be a set of missions as Campaign I. For Campaign II there will be new features centered around a more interactive build-able world on each level. .
New screenshot showing the three heavy defensive tower types: Auto-canon, Anti-Tank, and Howitzer. These base built towers will have the toughest armor, so I gave them unique designs from the other types of defensive units (coming soon)
