Loopstructor 2: Skyspine

Loopstructor 2: Skyspine is the full-fledged sequel to Loopstructor, bringing a fresh approach to tower defense built around track planning. Nuclear devastation has left the surface in ruins, but the world below is no safe haven. As creatures swarm your position, your defenses take the form of war trains racing along looping tracks. Plan their routes, combine your turrets, and bring the battlefield under fire.

LAY THE TRACKS. KEEP YOUR DEFENSES MOVING.

Connect stations across the battlefield to build a loop for each war train. Concentrate your fire in one area, or spread your trains across several routes to meet the swarm. You decide where the turrets go and where the trains run. Every lap brings another chance to strike.

STEAM, CHAIN ATTACKS, MISSILES. BUILD YOUR WAY.

Send steam turrets into battle, sweep through swarms with chain attacks, or rain down missiles and arcing shots. Different turret and upgrade combinations open up different ways to fight. With each choice of three rewards, strengthen a favorite setup or take your build in a new direction. Turn one choice after another into a train formation that packs a punch.

WATCH THE TURRETS TURN. WATCH THE SWARM CLOSE IN.

More grounded environments and striking creature designs give the underground battlefield a new look. Turrets now show different sides as they rotate to track enemies and open fire from moving trains. Up close, watch the machinery turn and the creatures advance. Pull back to see your entire formation trading fire with the swarm.
