Vectorius is a combo based action arcade game. Drop bombs on groups of enemies to create screen-filling chain reactions to stay alive. Your health bar is always decreasing and the only way to fill it back up is by triggering multi-enemy combos.

As your chain reactions grow, so does your multiplier. A higher multiplier means a higher score. A higher score means your health bar stays filled.
