Vortex Attack

Vortex Attack is a sci-fi shooter in which you pilot a ship and destroy vortices across the galaxies. You can play locally with up to three players. The game includes hundreds of levels, bosses and bonuses, with enemy waves that grow as each vortex expands.

The invasion

Alien war machines emerged from a vortex near the colony Vehar-12. In just over 20 Eartho-days, eighteen colonies have fallen and 56 million people have died. The machines are now approaching Earthos, the largest colony. After capturing a war machine, technicians discovered Lumergy, an energy that can both create and destroy vortices. You pilot a modified ship to collect Lumergy and use it to collapse the vortices and destroy the swarms inside them.

Push back the vortices

Each level centers on destroying a vortex, though some take several stages to eliminate. As a vortex grows, it sends increasingly large waves of enemies to overwhelm you. When you reach a stage where it can be destroyed completely, it unleashes its most dangerous swarm.

Destroy enemies to collect energy and send it toward the vortex. A blue sphere represents your level, while a red sphere represents the vortex level: delivered energy makes the blue sphere shrink the black hole, while the black hole continues to grow and stretch the blue sphere. The level ends when the blue sphere makes the red one disappear or the red sphere reaches its maximum size.

Ships and upgrades

You start with a choice of ships, and can unlock more by playing. There are 11 ship models, each upgradeable through four levels, as well as individual upgrades and ship add-ons.

• Vektar: A basic ship for novices with lots of health.
• Voxar: A fast Tier 1 ship with good multishot and many add-ons.
• Rozer: An average Tier 1 ship.
• Blaster: A strong Tier 1 ship with powerful bullets and few add-ons.
• Valkyr: A fast Tier 2 ship with few but powerful shots and good add-ons.
• Metr-81: A fast Tier 2 ship with average firepower and a powerful add-on.
• Kromaia: A fast Tier 2 ship with a powerful add-on and faster gameplay.
• Blaxar: A Tier 2 ship with heavy artillery, very powerful bullets and almost no add-ons.
• Verminest: A hard-to-handle, slow Tier 3 ship with few but powerful shots and the most add-ons.
• Beekyr: A weak, fast Tier 3 ship with heavy multishot.

Play and compete

The game is designed for multiplayer, with up to three players playing together locally. It also features online leaderboards and over 70 achievements, plus tournaments held through Steam or at fairs. Its presentation combines sci-fi particle effects with neo-retro effects and music. An arcade coin-op version was designed and integrated, with a physical machine hosted at Arcade Vintage in Petrer, Spain.
