About Voltswarm
Voltswarm is a single-player 3D bullet heaven about one small robot facing an ever-growing swarm of industrial machines. Your weapons aim and fire automatically, so survival depends on movement, positioning, threat reading, and the build choices you make under pressure.
Gameplay
Draft a starting weapon, collect XP from destroyed machines, and choose upgrades as the swarm grows denser. Combine up to two auto-firing weapons with stat-changing cores and behavior-changing mods. Collect gold, open tiered chests, visit The Scrapper's temporary shop, and activate optional boss portals when you are ready to raise the stakes.
Features
- Automatic weapons that keep the focus on movement and positioning
- 11 industrial-themed weapons with distinct attack patterns and upgrade paths
- Build-defining cores and mods across five rarity tiers
- A 3D voxel industrial-toy art style designed to keep large swarms readable
- Six regular enemy types, elites, and two summonable bosses
- Chests, XP collection, in-run gold, and The Scrapper's temporary shop
- A ten-minute survival run with escalating enemy density and optional repeated boss fights
- Keyboard and gamepad input with remappable controls
