Factorio Tower Defense ScenarioThis is factorio in a tower defense style scenario. I'm still working on it but it's playable and hopefully enjoyable. It was intended as a campaign level as you might find in other RTS games. As a result it is faster paced than sandbox mode and the factorio campaign levels and you will be entirely focused on building your defenses and holding off waves. The closest analogon is the wave defense scenario in vanilla, though this one has a few twists of its own. Biters will march on given paths straight to your rocket silo, you cannot build on the paths but you can build turrets and fire at them. Of course you'll also have to start mining resources to supply ammo and make more turrets. It will take about an hour or two depending on the difficulty level and wether you can live through it.
Can currently only be played in single player! The scenario is packaged as a mod. The scenario is almost entirely vanilla but it does include rocket turrets and as a side-effect of enabling the mod you can build those in the normal game too.
The following summarizes where the scenario is in terms of development.
You can find the source on github.
Finally, for this scenario I used factorio-stdlib and the rocket turret graphics from Predictabowl's Turrets Mod.
