Attack Programming is a technology that can be researched at the Fortress in Tech Level 4. It costs 400 Food and 200 Nova, and gives Workers +15 attack against buildings, Turrets, and Walls.

This technology makes Workers quite effective against buildings, but is of limited use, since Workers usually stay far away from the front lines - for good reason.

"This technology enhances your civilisation's worker units, granting them a substantial attack bonus against buildings and defensive structures such as Turrets and Walls."
