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. .
The Deployable Turret Carrier railcar is built at the player's railyard foundry, and then can place one defensive turret unit along the tracks anyplace on the map. This gives one more option to close a hole where enemy units can attack your lines. They can also be used as a rapid defense for setting up an attack, or emergency rebuilding.
