Cyberkast is a multiplayer free-for-all and dueling game, aimed at groups of 2-6 players wishing to have some seriously chaotic fun. Genre-wise, it combines elements of arcanoid, billiard, pong and even a tint of tower defense or strategy, resulting in a mix of arcadey and logical goodness. Flavour-wise, it's about deep space duels of cybernetically enhanced transhumans whose control over time, matter and energy has started to resemble sorcery.
Here you can see another solar matted based spell - Sunburst. It's the elongated one and, well, it's our sci-fi take on the fireball. It hits - it explodes in a huge circle of a fiery annihilation. The only problem is, it's overeager to explode so it pops on its first collision, whether you want it or not.
