Starfend

A Tower Defense That Becomes a Roguelite

Prepare your fleet, equip your stones, and level your skills. Then hold the line: place defensive drones and pilot your own combat drone against relentless waves of meteors. Clear the waves and Survival Mode begins, where you push as deep as you dare for rare loot. The deeper you go, the more it becomes a roguelite of builds, synergies, and risk.

NEW: Online Co-op (Open Beta)

Team up with up to 3 friends and defend one Earth together over Steam. Share a single run, hold the line side by side, and revive each other when a wave breaks through.

Co-op is a toolbox, not one fixed mode. Flip rules in the lobby, friendly fire, separate gold, per-player synergy, mirrored lanes, sudden death, and new modes appear on their own, from kill races to full PvP. Start from a preset, or share your ruleset with a code.

Online co-op is a free open beta in active development, and it is playable in the free demo, so you can try it before you buy.

Build a Different Run Every Time

In the Prepare Phase you build your drone from the ground up: pick a body, attach arms, and equip guns by color. Your colors decide your synergies, your firepower, and the upgrades open to you. There is no default loadout, every run starts with a decision.

Pilot It Actively

Your main drone is not a static turret. Fly it across the battlefield and keep it alive with three active abilities: Teleport out of incoming fire, raise a Shield when you need a hard stop, and spend gold to Repair on the fly. Meteors actively hunt you between waves, so stay mobile or lose it.

Wave Buff Cards

After each wave, choose 2 upgrade cards from 5 random options, split between cannon upgrades (crit, attack speed, power, range) and utility upgrades (drone speed, pickup range, cooldowns, instant repairs). With 48 cards and no fixed order, no two runs build the same.

Create Devastating Color Synergies

Combine drones of matching colors, Grey, Red, Green, Blue and 6 hybrids, to unlock global damage multipliers that amplify your entire fleet. Stack multiple synergies and the effect compounds. The deeper your color investment, the harder everything hits.

Hunt Giant Meteors

Giant Meteors appear throughout each run carrying powerful rewards. Destroy them before they escape to unlock active abilities and rare stones that can change the course of a run.

Grow Stronger Every Run

Between runs, invest in a persistent Skill Tree and a stone loadout system. Unlock new drone types, gun colors, hybrid combinations, and fleet upgrades. Every session builds your roster, even when you fall short.

If you enjoy the build depth of Brotato, the strategic layering of Dungeon Warfare 2, or the "one more run" pull of 20 Minutes Till Dawn, Starfend brings that same obsessive loop to 3D space tower defense.

Build your fleet. Hold the line. Then survive.
