Starfend

Starfend is a 3D space tower defense game that blends fleet building with roguelite runs. You place defensive drones and pilot your own combat drone to hold back waves of meteors. Clear the waves to enter Survival Mode, where you push deeper for rare loot and build synergies at increasing risk.

Prepare your fleet

During the Prepare Phase, you build your main drone by choosing a body, attaching arms and equipping guns by color. Your color choices determine your synergies, firepower and available upgrades, so each run starts with a loadout decision. You can also place and customize a fleet of autonomous defensive drones.

Pilot your drone

You fly your main drone across the battlefield rather than leaving it in place as a turret. Teleport lets you escape incoming fire, Shield provides a hard stop, and Repair spends gold to fix your drone during a run. Meteors actively hunt you between waves, so you need to stay mobile to keep your drone alive.

Upgrade each run

After every wave, you choose 2 upgrade cards from 5 random options. The 48-card pool includes cannon upgrades for critical hits, attack speed, power and range, as well as utility upgrades for drone speed, pickup range, cooldowns and instant repairs. With no fixed order, the cards offer different ways to shape each run.

You can combine drones of matching colors—Grey, Red, Green, Blue and 6 hybrids—to unlock global damage multipliers that strengthen your entire fleet. The effects compound when you stack synergies. Giant Meteors appear throughout each run; destroy them before they escape to earn powerful rewards, including active abilities and rare stones that can change the course of a run.

Progress between runs

Between runs, you invest in a persistent Skill Tree and a stone loadout system. These systems unlock new drone types, gun colors, hybrid combinations and fleet upgrades, building your roster even when you fall short. The game also includes Endless Survival Mode and Steam leaderboards.

Online co-op

The open beta supports online co-op for 2–4 players, who defend one Earth together in a shared run. You can revive each other when a wave breaks through. Lobby rules include friendly fire, separate gold, per-player synergy, mirrored lanes and sudden death; additional modes range from kill races to full PvP. Start with a preset or share a ruleset using a code.
