Vortex Attack is a frenetic arcade space shooter featuring explosive effects, an intense local multiplayer mode and online tournaments via Steam.

 

Game mechanics

The goal of each level is to close the vortices. Although some vortices will take several stages to close. Upon reaching a level where the vortex can be totally closed, it will unleash the most dangerous of its swarms to make things a lot harder for our players. The twist we’ve added in this game is that the vortex on each level will keep growing, throwing ever increasing waves of enemies to overwhelm the player, so that they must continually fight to push the vortex back. The game has been especially designed to play with up to 3 friends, although we’re considering adding an optional fourth player based on player feedback.

To implode the vortices, the player must destroy enemies to collect their energy. On top of the vortex there are two spheres: The player level (blue sphere) and the vortex level (red sphere). When the energy item sent by the player reaches the vortex, the blue sphere shrinks the black hole, symbolized with the red sphere. But in the other hand the black hole is constantly growing stretching the blue sphere. The game ends when the blue sphere makes the red one disappear or the red one grows to its maximum size. The concept is kind of new, reuses the concept based in Beekyr and improves it by removing the unnecessary bits.

The idea

After their first game Beekyr, Kaleidogames wanted to experiment with a more abstract space theme, whilst building on the successful gameplay of Beekyr. This resulted in the initial prototype for Vortex Attack, which they put in front of players at several game festivals. Even in this rough state, players were immediately captured by the game, with people playing all day long at each festival. Following that success, Kaleidogames decided to make it into a full game, including a local multiplayer mode that combines the best elements of competition and collaboration.
