Now it's time to play. When you enter the zone you're weak and easy pickings for stronger players. To charge up you'll need to fly around and collect various power-ups that give you things like stronger weapons, special abilities, and the like. You see every player has a bounty attached to them based on how strong they are and how many people they've killed. The more points you get, the better your score.
Continuum sounds simplistic, and it is, but that's also what makes it fun.
It's a guilty little pleasure that you can sneak away to and play for a few minutes and be done with.
