Your base is an extradimensional tank. Staying still is dangerous. Nothing will stop you.
Scenarios, maps, and puzzles.
"Error while running event level::on_gui_click (ID 1) ...Data/Roaming/Factorio/temp/currently-playing/control.lua:576: attempt to index field 'tank' (a nil value)"
Tank is gone! Gotta start over I think. Not sure what went wrong.
If biters nom the tank too hard it dies. Feed your upgrade chest repair packs to prevent this from happening.
Update adds a game over screen if the tank dies.
