Starfend is a 3D sci-fi tower defense roguelite where you build a fleet, pilot your own drone, and defend against endless waves of meteors. Every run is built from scratch, your choices before the first wave determine how the next thirty play out. Build Your Drone Before Each Run In the Prepare Phase, you build your main drone from the ground up. Pick a body, attach arms, and equip guns by color. The colors you choose determine your available synergies, your base firepower, and the upgrade paths open to you during the run. There's no default loadout, every run starts with a decision. Pilot It Actively Your main drone is not a static turret. You fly it across the battlefield and keep it alive. Three active abilities give you control under pressure: Teleport — blink out of incoming fire with a short cooldown Shield — manually block damage when you need a hard stop (Shift key) Repair — spend gold to restore hull integrity at any time Ambient meteors actively hunt your drone between and during waves. Stay mobile or lose it. Wave Buff Cards After each wave, choose 2 upgrade cards from 5 random options. Cards are split into two groups: Cannon upgrades (crit chance, attack speed, attack power, attack range, tied to the gun colors you own) and Utility upgrades (drone speed, pickup range, shield cooldown, teleport cooldown, instant repairs, and more). With 48 cards in the pool and no fixed order, each run builds differently. A sidebar tracks every buff you've stacked so you can see your build grow in real time. Stone Loadout System After each match, you gain 2 stones with randomized buff values. Collect crystals to buy more from the shop. Stones come in three tiers — Tier 1 grants 1 buff, Tier 2 grants 2, Tier 3 grants 3. Equip up to 30 stones across your drones (3 per drone, one of each tier) and filter by color and tier to assemble the exact loadout your build demands. Color Synergy Combat Combine drones of matching colors — Grey, Red, Green, Blue, and 6 hybrid variants, to unlock global damage multipliers that amplify your entire fleet. Stack multiple active synergies and the effect compounds. The deeper your color investment, the harder everything hits. Permanent Progression Between runs, invest resources into a persistent Skill Tree. Unlock new drone types, new gun colors, hybrid combinations, and fleet upgrades. Every session builds your roster, even when you fall short. Score and Compete Your final score reflects wave depth, game speed, and how well you protected your drone and earth under fire. A breakdown panel at the end of each run shows exactly where you scored and where you lost points. Climb the Steam leaderboard and fight for a spot in the Top 10. 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. No two runs. No two builds. No mercy.
