About This Demo

Get your first battle trains running in the demo. Connect stations, plan loops, and deploy turrets, then shape your firepower with enchantments and upgrades to face the oncoming monsters. Play the first chapter's campaign and experience the core loop, from laying tracks to putting a build together. Try different routes and combinations, and share what worked and what got in your way.

Loopstructor 2: Skyspine is the sequel to Loopstructor, a new take on tower defense built around rail planning. As monsters swarm in, your defenses are battle trains racing along the rails. Lay out loops, combine turrets, and bring the whole battlefield within firing range.

Lay the rails. Put your defenses in motion.

Connect stations scattered across the battlefield and give each battle train its own loop. Concentrate your fire on one position, or spread out across several routes to meet the swarm? You decide where the turrets go and where the trains run. Make every lap another attack.

Steam, chain attacks, missiles. Build your way.

Send steam turrets out in formation, sweep through swarms with chain attacks, or rain down missiles and arcing fire. Different turrets and upgrades create different ways to fight. Each round brings a choice of three: strengthen a setup you know, or try a new build? Turn those individual choices into battle trains with firepower that comes together.

Watch the turrets turn. Watch the swarm close in.

More realistic environments and more striking monsters give the battlefield a distinct new look. Compared with the original, turrets no longer show the same side at all times: as trains move along the rails, their turrets rotate toward enemies and open fire. Up close, see the machinery turn and the monsters lunge. Pull back to watch your battle trains exchange fire with the oncoming horde.
