Pylon Defense

CO-OP NOTE: Online co-op runs through Steam. Make sure Steam is open and you’re signed in before launching the game. To play together, one player starts the game. Everyone else opens their Steam friends list, right-clicks that player and chooses Join Game. Solo play works without Steam. (Steam may show you as playing “Spacewar”. That’s normal for now.)

PYLON DEFENSE

Hold the crater. Protect the pylon.

Deep in a lunar crater, a single pylon stands between humanity and the swarm. Wave after wave of alien horrors pour in from every direction, and it’s up to you, your guns, and whatever towers you can afford to keep it standing.

Pylon Defense is a first-person shooter crossed with tower defense. You’re not commanding from above: you’re on the ground, in the fight, sprinting between turret pads while the horde closes in.

FIGHT ON THE FRONT LINE

Take on crawlers, spitters, brutes and towering bosses with a pistol, rifle and shotgun. Customise each gun with sights, barrels and other attachments. Ammo isn’t free, so prep before every wave or get caught empty-handed when it matters most.

COLLECT CRYSTALS

Every kill drops crystals. Grab them before they fade, because they pay for everything: weapons, ammo, medkits and turrets.

BUILD YOUR DEFENSES

Bring terminals online to deploy Repeaters, Electric, Laser, MLRS, Mortar and Heavy Missile turrets. Upgrade them, repair them, and rebuild them when the swarm tears them down.

PLAY WITH FRIENDS

Team up with up to 3 friends in online co-op through Steam. Share the crystals, cover each other’s lanes, and say hi with the emote wheel between waves.

COLLECT MEMORIES

When the pylon falls, time rewinds, but you remember everything. Spend Memories on permanent upgrades to your turrets, economy, pylon and yourself, then go back in stronger.

How long can you hold? After wave 10 the swarm only gets tougher, and something out beyond the crater rim is watching…

ABOUT BITDRIVEN

BitDriven is a one-person studio. I’m a Computer Science for Games Development postgraduate trying to make my own way in the world, one game at a time.

As a solo developer, creating everything yourself is difficult, so I made Pylon Defense for Game Jam Plus 2026 in Unity, with art, audio and UI from some fantastic Asset Store creators, credited below.
