Gantry Protocol

2048 reimagined as a night shift in a mech factory. Push the whole 4x4 floor with the arrow keys or one swipe and every loose part slides at once, so two matching pieces weld into the next machine up the line. Bolts become drive gears, gears become servo arms, servos become fusion cells and armor plate, and past the 64 mark the scrap starts walking: Sentry Drone, Scout Walker, Guard Mech, Assault Walker, Siege Titan. Weld the 2048 Colossus and it strides out of your workshop under its own power, then keep going for the 4096 Omega at the top of the tech ladder. Every weld frees a bay and every new part takes one, so the shift ends when the floor is packed and nothing else fits. Twelve rungs of tech to light up, a workshop leaderboard for your heaviest shift, and one more run always waiting.
